RDMA/rxe: fix xa_alloc_cycle() error return value check again

Browse Source 
[ Upstream commit 1a685940e6200e9def6e34bbaa19dd31dc5aeaf8 ]

Currently rxe_alloc checks ret to indicate error, but 1 is also a valid
return and just indicates that the allocation succeeded with a wrap.

Fix this by modifying the check to be < 0.
