mtools: Patch out a useless sanity check

The sanity check is ensuring that filesystem size is divisible by
sectors-per-track. That seems to be just an optimization for ancient
media, and quite tricky to accomplish as different dosfstools versions
produce filesystems with different sectors-per-track.

Continue processing even if filesystem size is not divisible by
sectors-per-track.

+Subject: [PATCH] Continue even if fs size is not divisible by
+ sectors-per-track
+
+Filesystem with a size that is not divisible by sectors-per-track is
+not broken or invalid: it might be unoptimized on media where
+heads and cylinders actually matter but that should be it.
+
+Preserve the warning but make mtools continue even if fs size is not
+divisible by sectors-per-track.
