[IB] ib_umad: various cleanups

Browse source

Simplify user_mad.c code in a few places, and convert from kmalloc() +
memset() to kzalloc().  This also fixes a theoretical race window by
not accessing packet->length after posting the send buffer (the send
could complete and packet could be freed before we get to the return
statement at the end of ib_umad_write()).
