media: iris: Fix buffer count reporting in internal buffer check

Initialize the count variable to zero before counting unreleased
internal buffers in iris_check_num_queued_internal_buffers().
This prevents stale values from previous iterations and ensures accurate
error reporting for each buffer type. Without this initialization, the
count could accumulate across types, leading to incorrect log messages.
