Kernel TLS forms TLS header in kernel during encryption and removes
while decryption before giving packet back to user application. The
similar logic is introduced in chtls code as well.
v1->v2:
- tls_proccess_cmsg() uses tls_handle_open_record() which is not required
in TOE-TLS. Don't mix TOE with other TLS types.

This patch contains handling of first part or middle part of the record.
When we get a middle record, we will fetch few already sent bytes to
make packet start 16 byte aligned.
And if the packet has only the header part, we don't need to send it for
packet encryption, send that packet as a plaintext.
v1->v2:
- un-necessary updating left variable.
v3->v4:

TCP segment can chop a record in any order. Record can either be
complete or it can be partial (first part which contains header,
middle part which doesn't have header or TAG, and the end part
which contains TAG. This patch handles partial end part of a tx
record. In case of partial end part's, driver will send complete
record to HW, so that HW will calculate GHASH (TAG) of complete
packet.
Also added support to handle multiple records in a segment.
v1->v2:
- miner change in calling chcr_write_cpl_set_tcb_ulp.
- no need of checking return value of chcr_ktls_write_tcp_options.

When the kernel XTS implementation was extended to deal with ciphertext
stealing in commit 8083b1bf81 ("crypto: xts - add support for ciphertext
stealing"), a check was added to reject inputs that were too short.
However, in the vmx enablement - commit 2396684193 ("crypto: vmx/xts -
use fallback for ciphertext stealing"), that check wasn't added to the
vmx implementation. This disparity leads to errors like the following:
alg: skcipher: p8_aes_xts encryption unexpectedly succeeded on test vector "random: len=0 klen=64"; expected_error=-22, cfg="random: inplace may_sleep use_finup src_divs=[<flush>66.99%@+10, 33.1%@alignmask+1155]"
