RDMA: Pass entire uverbs attr bundle to create cq function
Changes the create_cq verb signature by sending the entire uverbs attr
bundle as a parameter. This allows drivers to send driver specific attrs
through ioctl for the create_cq verb and access them in their driver
specific code.
Also adds a new enum value for driver specific ioctl attributes for
methods already supporting UHW.

RDMA/mana_ib: Process QP error events in mana_ib
Process QP fatal events from the error event queue.
For that, find the QP, using QPN from the event, and then call its
event_handler. To find the QPs, store created RC QPs in an xarray.

RDMA/mana_ib: Use virtual address in dma regions for MRs
Introduce mana_ib_create_dma_region() to create dma regions with iova
for MRs. It allows creating MRs with any page offset. Previously,
only page-aligned addresses worked.
For dma regions that must have a zero dma offset (e.g., for queues),
mana_ib_create_zero_offset_dma_region() is added.
To get the zero offset, ib_umem_find_best_pgoff() is used with zero
pgoff_bitmask.
