btrfs-progs: tune: pass metadata_uuid in check_unfinished_fsid_change

Browse Source 
In preparation to use check_unfinished_fsid_change() to support the
ability to reunite devices after a failed 'btrfstune -m|M' command,
rename %unused2 to %metadata_uuid as the function
check_unfinished_fsid_change() write the metadata_uuid from the ctree to
it.
