Subject: IB/rxe: Fix a memory leak in rxe_qp_cleanup()

From: Bart Van Assche <bart.vanassche@sandisk.com>

commit e259934d4df7f99f2a5c2c4f074f6a55bd4b1722 upstream.

A socket is associated with every QP by the rxe driver but sock_release()
is never called. Add a call to sock_release() in rxe_qp_cleanup().

Fixes: commit 8700e3e7c48A5 ("Add Soft RoCE driver")
