Alberto Garcia 795be0621a quorum: Set sectors-count to 0 when reporting a flush error 
The QUORUM_REPORT_BAD event has fields to report the sector in which
the error was detected and the number of affected sectors starting
from that one. This is important for read and write errors, but not
for flush errors.

For flush errors the current code reports the total size of the disk
image. That is however not useful information in this case. Moreover,
the bdrv_getlength() call can fail, and there's no good way of
handling that failure.

Since we're reporting useless information and we cannot even guarantee
to do it in a consistent way, this patch changes the code to report 0
instead in all cases.
