[PATCH 2/3] btrfs-progs: prop: simplify parse_args()

[Satoru Takeuchi <takeuchi_satoru@jp.fujitsu.com>]

Since <object> parameter is mandatory for all subcommands,
'object' is always set by parse_args()'s callers.
In addition, on setting '*name' and '*value', if 'optind < argc'
is satisfied here, they are always set by parse_args()'s callers.
