quota: don't disable accounting with quotaoff

The quotaon(8) man page says:

NOTES ON XFS FILESYSTEMS
...
To turn off quota limit enforcement on any XFS filesys- tem, first make sure that quota accounting and enforce- ment are both turned on using repquota -v filesystem. Then, use quotaoff -v filesystem to disable limit
enforcement. This may be done while the filesystem is
mounted.

Turning on quota limit enforcement on an XFS filesystem is achieved using quotaon -v filesystem. This may be done while the filesystem is mounted

however, quotaoff turns off both enforcement -and- accounting, and then quotaon fails.

If the manpage describes the intended behavior, then I think the following patch is needed.
