Currently, bhyveload(8) does not validate the supplied disk
image path. For example, it allows passing the /dev/null
device, which later fails in userboot because it does not
support DIOCGSECTORSIZE and DIOCGMEDIASIZE ioctls (see
userdisk_init() in stand/userboot/userboot/userboot_disk.c).
Fix that by checking DIOCGSECTORSIZE and DIOCGMEDIASIZE ioctls early.
A similar check already exists in bhyve(8). While here, make
cb_diskioctl() report the obtained sector size instead of
hard-coding 512.
