git-completion.bash: pass $__git_subcommand_idx from __git_main()

Many completion functions perform hardcoded comparisons with $cword.
This fails in the case where the main git command is given arguments
(e.g. `git -C . bundle<TAB>` would fail to complete its subcommands).

Even _git_worktree(), which uses __git_find_on_cmdline(), could still
fail. With something like `git -C add worktree move<TAB>`, the
subcommand would be incorrectly identified as "add" instead of "move".

Assign $__git_subcommand_idx in __git_main(), where the git subcommand
is actually found and the corresponding completion function is called.
Use this variable to replace hardcoded comparisons with $cword.
