net/smc: fix up merge error with poll changes

My networking merge (commit cd50646bf823: "Pull networking fixes from
David Miller") got the poll() handling conflict wrong for af_smc.

The conflict between my 5bdec0811f4d ("Revert changes to convert to
->poll_mask() and aio IOCB_CMD_POLL") and Ursula Braun's 67f98918e75b
("net/smc: rebuild nonblocking connect") should have left the call to
sock_poll_wait() in place, just without the socket lock release/retake.

And I really should have realized that.  But happily, I at least asked
Ursula to double-check the merge, and she set me right.

This also fixes an incidental whitespace issue nearby that annoyed me
while looking at this.
