habanalabs: validate packet id during CB parse

[ Upstream commit bc75be24fa88ef10eecaff2b2a9ada8189e5ab5d ]

During command buffer parsing, driver extracts packet id
from user buffer. Driver must validate this packet id, since it is
being used in order to extract information from internal structures.
