marker: don't account destination linkto-file during internal migration
During a DHT re-balance operation, quota accounts for the destination. Problem of accounting this destination file are: 1) Migration is an internal operation, 'quota list' shows more usage on the CLI and this will come to the normal numbers once the migration is complete 2) If the usage is close to the limit set, then we can get 'Disk Quota Exceeded' errors in the I/O path during file migration Solution is we should not account of the usage on the destination file during migration, at the end of the migration. We need to reduce size of the source directory and accounting for the migrated dest file We assume that there are sufficent disk space in the back-end. DHT migrator should make sure that there are sufficient disk space before it starts the migration process.
