extblkdev/fcm: Refuse to operate on multimedia lvm block devices

BlueStore is selecting were data is put to the device.
Merging 2 FCM devices together means that BlueStore will see free space
on one of the devices, but not know the other is full and asking to put
data there. It will cause -ENOSPC while free space is reported.
