[PATCH 15/30] habanalabs: use common wrapper for MMU cache invalidation

[Oded Gabbay]

We have a common function that wraps the call to the MMU cache
invalidation function, which is ASIC-specific. The wrapper checks
the return value and prints error if necessary. For consistency, try
to use the wrapper when possible.
