fsck_ffs: Don't overrun mount device buffer
Maybe this case is impossible. Either way, when attempting to "/dev/"-prefix a
non-global device name, check that we do not overrun the f_mntfromname buffer.
In this case, truncating (with strlcpy or similar) would not be useful, since
the f_mntfromname result of getmntpt() is passed directly to open(2) later.
