rxe: fix error completion wr_id and qp_num

BugLink: https://bugs.launchpad.net/bugs/1837477
commit e48d8ed9c6193502d849b35767fd18e20bbd7ba2 upstream.

Error completions must still contain a valid wr_id and
qp_num such that the consumer can rely on. Correctly
fill these fields in receive error completions.
