quota: Convert __DQUOT_PARANOIA symbol to standard config option 

Make __DQUOT_PARANOIA define from the old days a standard config option
and turn it off by default.

This gets rid of a quota warning about writes before quota is turned on
for systems with ext4 root filesystem. Currently there's no way to legally
solve this because /etc/mtab has to be written before quota is turned on
on most systems.
