[TRIVIAL PATCH] sync_dquots_dev in Linux 2.4.21-pre7-ac1

[Pavel Roskin]

Hello!

I'm get this error if I compile 2.4.21-pre7-ac1 without CONFIG_QUOTA
defined:

fs/fs.o: In function `do_quotactl':
fs/fs.o(.text+0x1b362): undefined reference to `sync_dquots_dev'
make: *** [vmlinux] Error 1

sync_dquots_dev() is only implemented if CONFIG_QUOTA is defined.
However, quote.c uses it unconditionally.  include/linux/quotaops.h has
some macros to disable some functions when CONFIG_QUOTA is undefined, so
it's probably where the fix belongs.  This patch helps:
