quota: reorder flags in quota state
Flags in struct quota_state keep flags for each quota type and
some common flags. This patch reorders typed flags:
Before:
0 USRQUOTA DQUOT_USAGE_ENABLED
1 USRQUOTA DQUOT_LIMITS_ENABLED
2 USRQUOTA DQUOT_SUSPENDED
3 GRPQUOTA DQUOT_USAGE_ENABLED
4 GRPQUOTA DQUOT_LIMITS_ENABLED
5 GRPQUOTA DQUOT_SUSPENDED
6 DQUOT_QUOTA_SYS_FILE
7 DQUOT_NEGATIVE_USAGE
After:
0 USRQUOTA DQUOT_USAGE_ENABLED
1 GRPQUOTA DQUOT_USAGE_ENABLED
2 USRQUOTA DQUOT_LIMITS_ENABLED
3 GRPQUOTA DQUOT_LIMITS_ENABLED
4 USRQUOTA DQUOT_SUSPENDED
5 GRPQUOTA DQUOT_SUSPENDED
6 DQUOT_QUOTA_SYS_FILE
7 DQUOT_NEGATIVE_USAGE
Now we can get bitmap of all enabled/suspended quota types without loop.
For example suspended: (flags / DQUOT_SUSPENDED) & ((1 << MAXQUOTAS) - 1).
