io_uring: fix two assignments in if conditions
commit df730ec21f7ba395b1b22e7f93a3a85b1d1b7882 upstream.
Fixes two errors:
"ERROR: do not use assignment in if condition
130: FILE: io_uring/net.c:130:
+ if (!(issue_flags & IO_URING_F_UNLOCKED) &&
ERROR: do not use assignment in if condition
599: FILE: io_uring/poll.c:599:
+ } else if (!(issue_flags & IO_URING_F_UNLOCKED) &&"
reported by checkpatch.pl in net.c and poll.c .
