rpc/socket.c : Bonnie++ hangs during rewrites in ganesha + SSL
Problem: Bonnie++ rewrite operation hangs in ganesha + SSL environment
Solution: Bonnie++ hangs during execution of rewrite operation in
ganesha + SSL environment.It was hanged due to blocking on poll
call in ssl_do because no POLLOUT event was getting on socket.
Socket is not getting POLLOUT event because all other threads
are waiting to get lock and lock is not released ssl_do
because it is not getting any event on poll.To correct it
update the condition in ssl_do as same in getting error
SSL_ERROR_WANT_READ.
Test: To test the patch followed below procedure
1) Setup 2X2 Ganesha + SSL environment.
2) Run bonnie from 3 nfs client parallely
3) After run "Rewwrite operation" by bonnie it is hanged.
4) After apply the patch it is not hanged.
BUG: 1418213
