mptfusion: enable no_write_same for vmware scsi disks
commit 4089b71cc820a426d601283c92fcd4ffeb5139c2 upstream.
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.
