io_uring: fix xa_alloc_cycle() error return value check

[ upstream commit a30f895ad3239f45012e860d4f94c1a388b36d14 ]

We currently check for ret != 0 to indicate error, but '1' is a valid
return and just indicates that the allocation succeeded with a wrap.
Correct the check to be for < 0, like it was before the xarray
conversion.
