[sheepdog] [PATCH] collie: correct command-line options parser

[ChenZhe]

From: ChenZhe <chenzhe at xinnet.com>

"collie cluster recover disable -p7001" not work.
getopt_long() will reorder the options in argv.
so, we need to skip one more argument before getopt() for the subcmd who need third arg.
