btrfs-progs: add quota-related info to usage messages
Extending usage messages with some info on the quota functionality:
- The -i option of "subvol create" and "subvol snapshot" was not
documented
- The -c option of "qgroup limit" is the default option
- The "qouta rescan" command is not yet implemented, while it should be
executed after enabling quota on a non-empty filesystem.
