[PATCH][next] ASoC: max98388: Fix missing increment of variable slot_found

[Colin Ian King]

The variable slot_found is being initialized to zero and inside
a for-loop is being checked if it's reached MAX_NUM_CH, however,
this is currently impossible since slot_found is never changed.
In a previous loop a similar coding pattern is used and slot_found
is being incremented. It appears the increment of slot_found is
missing from the loop, so fix the code by adding in the increment.
