qtest/ahci: rename 'Command' to 'CommandHeader'

The structure name is a bit of a misnomer; the structure currently named
command is actually the commandheader. A future patch in this series
will add an actual "Command" structure, so we'll rename it now before the
rest of the functions in this series try to use it.

In addition, rename the "b1" and "b2" fields
to be a unified uint16_t named "flags."
