[PATCH v4] xfsprogs: xfs_quota command error message improvement

Bill O'Donnell
2020-07-01T12:50:12Z

Make the error messages for rudimentary xfs_quota commands
(off, enable, disable) more user friendly, instead of the
terse sys error outputs.

v4: include ENOSYS for disable, enable, and OFF cases
v3: remove EINVAL from the OFF case
v2: enable internationalization and capitalize new message strings
