[sheepdog] [PATCH] collie: fix optional third para parsing

[Liu Yuan]

From: Liu Yuan <tailai.ly at taobao.com>

For command like 'collie vdi list [vdiname]', the third para [vdiname] is
optinal, so we should not strickly check third argument existence even if
SUBCMD_FLAG_NEED_THIRD_ARG is not set. Otherwise, 'collie vdi list test' will
not be functional.
