net/tls: pass record number as a byte array
TLS offload code casts record number to a u64. The buffer
should be aligned to 8 bytes, but its actually a __be64, and
the rest of the TLS code treats it as big int. Make the
offload callbacks take a byte array, drivers can make the
choice to do the ugly cast if they want to.
Prepare for copying the record number onto the stack by
defining a constant for max size of the byte array.
