When HTC packet is sent to CE for physical tx, the tx compl
interrupt can get triggered very quickly, resulting the
HTC buffer being freed at a very early time. Any memory
access into the same HTC buffer after HTC tx compl returns
will be a use-after-free case.
Relocate all HTC packet touching code to places before
it gets populated to CE for tx.
