Dan Carpenter 1d5c69514e RDMA/mana_ib: Use safer allocation function() ...

My static checker says this multiplication can overflow.  I'm not an
expert in this code but the call tree would be:

ib_uverbs_handler_UVERBS_METHOD_QP_CREATE() <- reads cap from the user
-> ib_create_qp_user()
   -> create_qp()
      -> mana_ib_create_qp()
         -> mana_ib_create_ud_qp()
            -> create_shadow_queue()

It can't hurt to use safer interfaces.
