As noted in the "Deprecated Interfaces, Language Features, Attributes, and
Conventions" documentation [1], size calculations (especially
multiplication) should not be performed in memory allocator (or similar)
function arguments due to the risk of them overflowing. This could lead to
values wrapping around and a smaller allocation being made than the caller
was expecting. Using those allocations could lead to linear overflows of
heap memory and other misbehaviors.
Use the purpose specific kcalloc() function instead of the argument count *
size in the kzalloc() function.

The kernel test robot flagged an warning for ".../efc_device.c:932:6:
warning: cast to smaller integer type 'enum efc_nport_topology' from 'void
*'"
For the topology events, the "arg" field is generically defined as a void *
and is used to pass different arguments. Most of the arguments are pointers
to data structures. But for the EFC_EVT_NPORT_TOPOLOGY_NOTIFY event, the
argument is an enum value, and the code is typecasting the void * to an
enum generating the warning.
Fix by converting the EFC_EVT_NPORT_TOPOLOGY_NOTIFY event to pass a pointer
to the enum, thus it's a straight-forward pointer dereference in the event
handler.

Add library interface definitions for:
- Fabric node initialization and logins.
- Name/Directory Services node.
- Fabric Controller node to process rscn events.
These are all interactions with remote ports that correspond to well-known
fabric entities
