Parav Pandit 670ebdf0c4 RDMA/core: Do not expose unsupported counters
[ Upstream commit 0f6ef65d1c ]

If the provider driver (such as rdma_rxe) doesn't support pma counters,
avoid exposing its directory similar to optional hw_counters directory.
If core fails to read the PMA counter, return an error so that user can
retry later if needed.

Fixes: 35c4cbb178 ("IB/core: Create get_perf_mad function in sysfs.c")
