block: rename BlockAcctType members to start with BLOCK_ instead of BDRV_

Browse Source 
The middle term goal is to move the BlockAcctStats structure in the device models.
(Capturing I/O accounting statistics in the device models is good for billing)
This patch make a small step in this direction by removing a reference to BDRV.
