fs/adfs: dir: add common directory sync method
adfs_fplus_sync() can be used for both directory formats since we now have a common way to access the buffer heads, so move it into dir.c and appropriately rename it. Remove the directory-format specific implementations. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
