ecryptfs_exorcise_daemon() drops queued messages from a dying daemon
without holding ecryptfs_msg_ctx_lists_mux, but
ecryptfs_msg_ctx_alloc_to_free() requires that lock.
Take the list lock while moving the queued contexts back to the free
list to avoid racing with other global msg ctx list users.
Fixes: f66e883eb6 ("eCryptfs: integrate eCryptfs device handle into the module.")
