RDMA/uverbs: Fix false error in query gid IOCTL

RDMA/uverbs: Fix false error in query gid IOCTL

Some drivers (such as EFA) have a GID table, but aren't IB/RoCE devices.
Remove the unnecessary rdma_ib_or_roce() check.

This fixes rdma-core failures for EFA when it uses the new ioctl interface
for querying the GID table.
