libqos/ahci: Swap memread/write with bufread/write
Where it makes sense, use the new faster primitives.
For generally small reads/writes such as for the PRDT
and FIS packets, stick with the more wasteful but
easier to debug memread/memwrite.
For ahci-test (before migration tests):
With this patch:
real 0m3.675s
user 0m2.582s
sys 0m1.718s
Without any qtest protocol improvements:
real 0m14.171s
user 0m12.072s
sys 0m12.527s
