Mike Frysinger e8aec37165 cros_sdk: skip unmount phase if no mounts are found
Normally safe_umount_tree isn't called if there are no mount points in the
chroot, but there are some edge cases (like early setup errors) where it
may be possible.  So add a simple check to make sure that there are mount
points for us to work on before calling umount.

BUG=None
TEST=add early `die` before mounts; see no umount error output
