[PATCH] habanalabs: fix debugfs code

This fixes multiple things in the habanalabs debugfs code, in particular: - mmu_write() was unnecessarily verbose, copying around between multiple buffers - mmu_write() could write a user-specified, unbounded amount of userspace memory into a kernel buffer (out-of-bounds write) -
