Title: allocate 4096 bytes for 4k alligned devices

To make 4k scsi devices to work, allocated memory needs to be increased
accordingly

Tested in the following scenario:

modprobe scsi_debug dev_size_mb=100 sector_size=4096

parted /dev/sdc u b p
Model: Linux scsi_debug (scsi)
Disk /dev/sdc: 209715200B
Sector size (logical/physical): 4096B/4096B
Partition Table: msdos

Number Start End Size Type File system Flags
1 262144B 2097151B 1835008B primary boot,
prep, type=41
2 2097152B 200015871B 197918720B primary type=83

qemu-system-ppc64 -enable-kvm -M pseries -m 1024 -nographic -drive
file=/dev/sdc,if=none,format=raw,id=drive-scsi0 -device
scsi-block,drive=drive-scsi0,id=scsi0 -vga none
