[SWDEV-479204] Fix the hipGraph AQL package fill issue

This patch fixes this potential issue that filling AQL header before
filling the AQL body. The hsa spec specifies "Packet processors may
process AQL packets after the packet format field is updated, but
before the doorbell is signaled."
However, the hipGraph AQL package with valid header will be filled
before fill the body, which may have the potential issue that CP
receive invalid AQL body.
