xdp: obtain the mem_id mutex before trying to remove an entry.
[ Upstream commit 86c76c09898332143be365c702cf8d586ed4ed21 ] A lockdep splat was observed when trying to remove an xdp memory model from the table since the mutex was obtained when trying to remove the entry, but not before the table walk started: Fix the splat by obtaining the lock before starting the table walk. Fixes: c3f812cea0d7 ("page_pool: do not release pool until inflight == 0.")
