accel/habanalabs: remove old interface variation of 'access_ok()' 



The access_ok() API no longer requires the VERIFY_WRITE argument,
and the use of the old interface with VERIFY_WRITE is deprecated.

Clean up the habanalabs memory manager to use the modern access_ok()
interface consistently. This removes old #ifdef guards and aligns the
driver with current upstream kernel APIs.
