io_uring/rw: fix error'ed retry return values
[ upstream commit 62bb0647b14646fa6c9aa25ecdf67ad18f13523c ]
Kernel test robot reports that we test negativity of an unsigned in
io_fixup_rw_res() after a recent change, which masks error codes and
messes up the return value in case I/O is re-retried and failed with
an error.
Fixes: 4d9cb92ca41dd ("io_uring/rw: fix short rw error handling")
