Parav Pandit a840c93ca7 IB/core: Fix error code for invalid GID entry
When a GID entry is invalid EAGAIN is returned. This is an incorrect error
code, there is nothing that will make this GID entry valid again in
bounded time.

Some user space tools fail incorrectly if EAGAIN is returned here, and
this represents a small ABI change from earlier kernels.

The first patch in the Fixes list makes entries that were valid before
to become invalid, allowing this code to trigger, while the second patch
in the Fixes list introduced the wrong EAGAIN.

Therefore revert the return result to EINVAL which matches the historical
expectations of the ibv_query_gid_type() API of the libibverbs user space
library.
