[ofa-general] [PATCH] IB/core - remove redundant NULL pointer check in ib_mad_recv_done_handler()

[Ralph Campbell]

In ib_mad_recv_done_handler(), the response pointer is checked for
NULL after allocating it.  It is then checked again in the local
process_mad() path but there is no possibility of it changing
in between.
