This is already checked for LVM and ZFS setups, but not for Btrfs. Add
it there too, as it doesn't work anyway.
Tested by creating a block device with 4K sectorsize using
the following QEMU args:
-device virtio-blk,drive=testdrive4k,logical_block_size=4096,physical_block_size=4096
-drive file=/path/to/4k-testdisk.img,if=none,id=testdrive4k
The 4k-testdisk.img was created with:
qemu-img create -f qcow2 /path/to/4k-testdisk.img 16G
