Subject: [PATCH rdma-next 1/1] RDMA/mana_ib: take CQ type from the device type

From: Konstantin Taranov <kotaranov@...rosoft.com>

Get CQ type from the used gdma device. The MANA_IB_CREATE_RNIC_CQ
flag is ignored. It was used in older kernel versions where
the mana_ib was shared between ethernet and rnic.

Fixes: d4293f96ce0b ("RDMA/mana_ib: unify mana_ib functions to support any gdma device")
