sleep-config: fix useless check for swapfile type

Since 0c6f1f4ea4 the check was useless, because the kernel will
ever only write "partition" or "file" there.

OTOH, it is possible that "\\040(deleted)" (escaped " (deleted)")
will be added for removed files. This should not happen, so add
a warning to detect those cases.
