Subject: [PATCH 2.6.24] RDMA/cxgb3: Set the max_qp_init_rd_atom attribute.

RDMA/cxgb3: Set the max_qp_init_rd_atom attribute.

Attribute max_qp_init_rd_atom is not getting set.  Version 1.0.4 of
librdmacm now validates the user's requested initiator and responder
resources vs the max supported by the device.  Since iw_cxgb3 wasn't
setting this attribute (and it defaulted to 0), all rdma_connect()s fail
if there are initiator resources requested by the app.
