RDMA/bnxt_re: Report supported value to IB stack in query_device
- Report supported value for max_mr_size to IB stack in query_device.
Also, check and log if MR size requested by application in
reg_user_mr() is greater than value currently supported by driver.
- Report only 4K page size support for now
- Fix Max_QP value returned by ibv_devinfo -vv.
In case of PF, FW reserves 129 QPs for creating QP1s of VFs
and PF. So the max_qp value reported by FW for PF doesn'tt include
the QP1. Fixing this issue by adding 1 with the value reported
by FW.
