fat: Cleanup FAT attribute stuff
This adds three helpers: fat_make_attrs() - makes FAT attributes from inode. fat_make_mode() - makes mode_t from FAT attributes. fat_save_attrs() - saves FAT attributes to inode. Then this replaces: MSDOS_MKMODE() by fat_make_mode(), fat_attr() by fat_make_attrs(), ->i_attrs = attr & ATTR_UNUSED by fat_save_attrs(). And for root inode, those is used with ATTR_DIR instead of bogus ATTR_NONE.
