From: Konstantin Taranov <kotaranov@xxxxxxxxxxxxx>
This patch aims to address two issues in mana_ib:
1) Unsafe and inconsistent access to gdma_dev and gdma_context
2) Code repetitions
As a rule of thumb, functions should not access gdma_dev directly
Introduced functions:
1) mdev_to_gc
2) mana_ib_get_netdev
3) mana_ib_install_cq_cb
Signed-off-by: Konstantin Taranov <kotaranov@xxxxxxxxxxxxx>

v1->v2: Sorry that was sent again, I forgot to add RDMA/mana_ib to the subject
v2->v3: missing changes in qp.c
