Call scnprintf() instead of snprintf() since the latter may return
an incorrect count in cases where the write is truncated to fit.

scnprintf() returns the count of what was actually written;
snprintf() returns the count of what would have been written.

When using a virtual SCSI disk in a VMWare VM if blkdev_issue_zeroout is used
data can be improperly zeroed out using the mptfusion driver. This patch
disables write_same for this driver and the vmware subsystem_vendor which
ensures that manual zeroing out is used instead.
