RDMA/efa: Add Completion Counters support
Implement completion counters for the EFA device. Each completion
counter is backed by two EFA event counters, one for success
completions and one for error completions.
The driver creates umem for counters from private descriptor ioctl
attributes using core utility.
Read operations are not implemented as the counter values are accessed
directly from userspace through the mapped memory.
