caif: Bugfix list_del_rcu race in cfmuxl_ctrlcmd.
Always use cfmuxl_remove_uplayer when removing a up-layer. cfmuxl_ctrlcmd() can be called independently and in parallel with cfmuxl_remove_uplayer(). The race between them could cause list_del_rcu to be called on a node which has been already taken out from the list. That lead to a (rare) crash on accessing poisoned node->prev inside list_del_rcu. This fix ensures that deletion are done holding the same lock.
