Subject[226/262] xen/blkback: Report VBD_WSECT (wr_sect) properly.
3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>

commit 5c62cb48602dba95159c81ffeca179d3852e25be upstream.

We did not increment the amount of sectors written to disk
b/c we tested for the == WRITE which is incorrect - as the
operations are more of WRITE_FLUSH, WRITE_ODIRECT. This patch
fixes it by doing a & WRITE check.
