David Howells 0b7ec177b5 crypto: algif_hash - Fix race between MORE and non-MORE sends 
The 'MSG_MORE' state of the previous sendmsg() is fetched without the
socket lock held, so two sendmsg calls can race.  This can be seen with a
large sendfile() as that now does a series of sendmsg() calls, and if a
write() comes in on the same socket at an inopportune time, it can flip the
state.

Fix this by moving the fetch of ctx->more inside the socket lock.

Fixes: c662b043cd ("crypto: af_alg/hash: Support MSG_SPLICE_PAGES")
