The opcode iopoll_queue flag is now redundant with REQ_F_IOPOLL. Only
io_{read,write}{,_fixed}() and io_uring_cmd() set the REQ_F_IOPOLL flag,
and the opcodes with these ->issue() implementations are precisely the
ones that set iopoll_queue. So don't bother checking the iopoll_queue
flag in io_issue_sqe(). Remove the unused flag from struct io_issue_def.
