io_uring: unify fsize with def->work_flags
This one was missed in the earlier conversion, should be included like
any of the other IO identity flags. Make sure we restore to RLIM_INIFITY
when dropping the personality again.
Fixes: 98447d65b4a7 ("io_uring: move io identity items into separate struct")
