"sense_len" was declared as int type but actually it only stores a
u16 value that comes from hardware. The cast to u16 in min_t()
confuses static analysis because it truncates the int to u16 so I've
fixed the declaration to reflect that "sense_len" is just a u16.
Also there was a call to cpu_to_be16() which I've changed to
be16_to_cpu(). The functions are equivalent, but obviously the
hardware is big endian and we're doing the min_t() comparison on CPU
endian values.
This whole patch is just a cleanup and doesn't affect how the code
works.

* 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending:
target: Convert to DIV_ROUND_UP_SECTOR_T usage for sectors / dev_max_sectors
kernel.h: Add DIV_ROUND_UP_ULL and DIV_ROUND_UP_SECTOR_T macro usage
iscsi-target: Add iSCSI fabric support for target v4.1
iscsi: Add Serial Number Arithmetic LT and GT into iscsi_proto.h
iscsi: Use struct scsi_lun in iscsi structs instead of u8[8]
iscsi: Resolve iscsi_proto.h naming conflicts with drivers/target/iscsi
struct scsi_lun is also just a struct with an array of 8 octets (64 bits)
but using it instead in iscsi structs lets us call scsilun_to_int
without a cast, and also lets us copy it using assignment, instead of
memcpy().

This patch renames the following iscsi_proto.h structures to avoid
namespace issues with drivers/target/iscsi/iscsi_target_core.h:
*) struct iscsi_cmd -> struct iscsi_scsi_req
*) struct iscsi_cmd_rsp -> struct iscsi_scsi_rsp
*) struct iscsi_login -> struct iscsi_login_req
This patch includes useful ISCSI_FLAG_LOGIN_[CURRENT,NEXT]_STAGE*,
and ISCSI_FLAG_SNACK_TYPE_* definitions used by iscsi_target_mod, and
fixes the incorrect definition of struct iscsi_snack to following
RFC-3720 Section 10.16. SNACK Request.
Also, this patch updates libiscsi, iSER, be2iscsi, and bn2xi to
use the updated structure definitions in a handful of locations.

be2iscsi passes the boot functions its phba object which is
allocated in the shost, but iscsi_ibft passes in a object
allocated for each item to display. The problem is that
iscsi_boot_sysfs was managing the lifetime of the object
passed in and doing a kfree on release. This causes a double
free for be2iscsi which frees the shost in its pci_remove.
This patch fixes the problem by adding a release callback
which the drivers can call kfree or a put() type of function
(needed for be2iscsi which will do a get/put on the shost).
