[PATCH] fs/quota: update quota state flags scheme with project quota flags

From: Roman Anufriev
Date: Sat Oct 17 2020 - 23:15:16 EST


Current quota state flags scheme doesn't include project quota and thus
shows all flags after DQUOT_USAGE_ENABLED wrong. Fix this and also add
DQUOT_NOLIST_DIRTY to the scheme.
