[ALSA] fixes als100 not detecting opl3

ALS100 driver
This patch fixes issue when opl3 device couldn't be found
due to numbering of devices in pnp card, because search of
opl3 device started from mpu device, which could have number
greater than opl3 could.

Example:
MPU is 00:01.03
and
OPL is 00:01.01
