tls: Factor tls_strp_msg_consume() from tls_strp_msg_done()

tls_strp_msg_done() conflates releasing the current record with
checking for the next one via tls_strp_check_rcv(). A subsequent
patch needs to release a record without immediately triggering
that check, so the release step is separated into
tls_strp_msg_consume(). tls_strp_msg_done() is preserved as a
wrapper for existing callers.
