IB/rxe: Add support for zero-byte operations
The last_psn algorithm fails in the zero-byte case: it calculates
first_psn = N, last_psn = N-1. This makes the operation unretryable since
the res structure will fail the (first_psn <= psn <= last_psn) test in
find_resource().
While here, use BTH_PSN_MASK to mask the calculated last_psn.
