[PATCH] libata: make the owner of a qc responsible for freeing it
qc used to be freed automatically on command completion. However, as
a qc can carry information about its completion status, it can be
useful to its owner/issuer after command completion. This patch makes
freeing qc responsibility of its owner. This simplifies
ata_exec_internal() and makes command turn-around for atapi request
sensing less hackish.
