ALSA: pci: lx6464es: fix a debug loop
[ Upstream commit 5dac9f8dc25fefd9d928b98f6477ff3daefd73e3 ]
This loop accidentally reuses the "i" iterator for both the inside and
the outside loop. The value of MAX_STREAM_BUFFER is 5. I believe that
chip->rmh.stat_len is in the 2-12 range. If the value of .stat_len is
4 or more then it will loop exactly one time, but if it's less then it
is a forever loop.
It looks like it was supposed to combined into one loop where
conditions are checked.
