====================
net/tls: minor micro optimizations

This set brings a number of minor code changes from my tree which
don't have a noticeable impact on performance but seem reasonable
nonetheless.

First sk_msg_sg copy array is converted to a bitmap, zeroing that
structure takes a lot of time, hence we should try to keep it
small.

Next two conditions are marked as unlikely, GCC seemed to had
little trouble correctly reasoning about those.

Patch 4 adds parameters to tls_device_decrypted() to avoid
walking structures, as all callers already have the relevant
pointers.

Lastly two boolean members of TLS context structures are
converted to a bitfield.
