* grub-core/kern/emu/hostdisk.c (grub_util_get_fd_size): Adapt for

mingw32 as well based on grub_util_get_disk_size.
	* util/misc.c (grub_util_get_disk_size): Removed. all users switched to
	grub_util_get_fd_size.
	(sync): Removed.
	(fsync): Moved to ...
	* grub-core/kern/emu/misc.c (fsync): ... here.
