ALSA: rawmidi: Change resized buffers atomically
commit 39675f7a7c7e7702f7d5341f1e0d01db746543a0 upstream.
The SNDRV_RAWMIDI_IOCTL_PARAMS ioctl may resize the buffers and the
current code is racy. For example, the sequencer client may write to
buffer while it being resized.
As a simple workaround, let's switch to the resized buffer inside the
stream runtime lock.
