io_uring/rw: fix wrong NOWAIT check in io_rw_init_file()
Commit ae6a888a4357131c01d85f4c91fb32552dd0bf70 upstream.
A previous commit improved how !FMODE_NOWAIT is dealt with, but
inadvertently negated a check whilst doing so. This caused -EAGAIN to be
returned from reading files with O_NONBLOCK set. Fix up the check for
REQ_F_SUPPORT_NOWAIT.
