tls: don't rely on tx_work during send()
[ Upstream commit 7f846c65ca11e63d2409868ff039081f80e42ae4 ]
With async crypto, we rely on tx_work to actually transmit records
once encryption completes. But while send() is running, both the
tx_lock and socket lock are held, so tx_work_handler cannot process
the queue of encrypted records, and simply reschedules itself. During
a large send(), this could last a long time, and use a lot of memory.
Transmit any pending encrypted records before restarting the main
loop of tls_sw_sendmsg_locked.
Fixes: a42055e8d2c3 ("net/tls: Add support for async encryption of records for performance")
