Takashi Iwai 5568147015 ALSA: msnd: Optimize / harden DSP and MIDI loops ...

commit 20e2b79179 upstream.

The ISA msnd drivers have loops fetching the ring-buffer head, tail
and size values inside the loops.  Such codes are inefficient and
fragile.

This patch optimizes it, and also adds the sanity check to avoid the
endless loops.
