io_uring: remove dead non-zero 'poll' check

Browse Source 
Colin reports that Coverity complains about checking for poll being
non-zero after having dereferenced it multiple times. This is a valid
complaint, and actually a leftover from back when this code was based
on the aio poll code.

Kill the redundant check.
