IB/core: Introduce GID attribute get, put and hold APIs
This patch introduces three APIs, rdma_get_gid_attr(), rdma_put_gid_attr(), and rdma_hold_gid_attr() which expose the reference counting for GID table entries to the entire stack. The kref counting is based on the struct ib_gid_attr pointer Later patches will convert more cache query function to return struct ib_gid_attrs.
