ALSA: mixart: range checking proc file
commit b0cc58a25d04160d39a80e436847eaa2fbc5aa09 upstream.
The original code doesn't take into consideration that the value of
MIXART_BA0_SIZE - pos can be less than zero which would lead to a large
unsigned value for "count".
Also I moved the check that read size is a multiple of 4 bytes below
the code that adjusts "count".
