Takashi Iwai 20e2b79179 ALSA: msnd: Optimize / harden DSP and MIDI loops 
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.
