Expand HAMMER filesystem step 1/2

Format the volume and increase other volumes' vol_count field.
The space of the new volume is not yet given to the filesystem (that's step 2).

Example:

newfs_hammer -L TEST /dev/da0
mount_hammer /dev/da0 /hammer
hammer expand /hammer /dev/da1
umount /hammer
mount_hammer /dev/da0:/dev/da1 /hammer

# the following fails (wrong number of volumes)
mount_hammer /dev/da0 /hammer
