_gid_table_setup_one() only performs GID table cache memory allocation,
marks entries as invalid (free) and marks the reserved entries.
At this point GID table is empty and no entries are added.

On dual port device if _gid_table_setup_one() fails to allocate the gid
table for 2nd port, there is no need to perform cleanup_gid_table_port()
to delete GID entries, as GID table is empty.
Therefore make use of existing gid_table_release_one() routine which
frees the GID table memory and avoid code duplication.
