Takashi Iwai 4d21d905a0 ALSA: seq: Fix potential concurrent access to the deleted pool ...

commit 75545304eb upstream.

The input pool of a client might be deleted via the resize ioctl, the
the access to it should be covered by the proper locks.  Currently the
only missing place is the call in snd_seq_ioctl_get_client_pool(), and
this patch papers over it.
