Move a few more things so we can make them static and clear exfat.h out.
At this point, pretty much everything that can be static is static.
(Note: FAT_sync(), buf_sync(), and sync_alloc_bitmap() aren't called
anyplace, but aren't static because (a) that will toss an error and
(b) they probably *should* be getting called someplace

This patch avoids that core component modules are being unloaded
while the related configfs interface has active items in its directories.
It is needed to prevent the situation where the core module cannot
be unloaded anymore, because the reference count 'used by' indicates that
the module is still being used and the usage count cannot be decreased by
calling rmdir, as the configfs directory has already been removed.
