rebase: remove useless arguments check

Remove a check on the number of arguments for --onto and -x options.
It is not possible for $# to be <= 2 at this point :

 - if --onto or -x has an argument, git rev-parse --parseopt will
   provide something like this :
     set -- --onto 'x' --
   when parsing the "--onto" option, $# will be 3 or more if there are
   other options.

 - if --onto or -x doesn't have an argument, git rev-parse --parseopt
   will exit with an error and display usage information.
