Potential NULL pointer deference in RDMA

Hi All:
drivers/infiniband/sw/rxe/rxe_verbs.c:
The function to_rdev() could return NULL, but no caller in this file
checks the return value but directly dereference them, which seems
potentially unsafe. Callers include rxe_query_device(),
rxe_query_port(), rxe_query_pkey(), etc.
