Fix zpool subcommands error message with some unsupported options 

Both 'detach' and 'online' zpool subcommands, when provided with an
unsupported option, forget to print it in the error message:

   # zpool online -t rpool vda3
   invalid option ''
   usage:
      online [-e] <pool> <device> ...

This changes fixes the error message in order to include the actual
option that is not supported.
