RDMA/mana_ib: Prevent array underflow in mana_ib_create_qp_raw()

Browse source

The "port" comes from the user and if it is zero then the:

	ndev = mc->ports[port - 1];

assignment does an out of bounds read.  I have changed the if
statement to fix this and to mirror how it is done in
mana_ib_create_qp_rss().
