Commit 732e26b98e5c79a4298dbe341f43b54b354bb241 added checks to
prevent e2fsck from being run in filesystem-modifying mode against
a mounted or otherwise busy device, due to several bug reports of
users doing this even with the verbose warnings in check_mount().
However, it also prevented e2fsck from checking a mounted root
filesystem, which will prevent the node from booting. Once again
allow e2fsck to run against the mounted root filesystem.
