ALSA: asihpi: Fix potential OOB array access

[ Upstream commit 7b986c7430a6bb68d523dac7bfc74cbd5b44ef96 ]

ASIHPI driver stores some values in the static array upon a response
from the driver, and its index depends on the firmware. We shouldn't
trust it blindly.

This patch adds a sanity check of the array index to fit in the array
size.
