[PATCH] builtin/worktree.c: fix a sparse '0 as NULL pointer' warning

Hi Eric,

If you need to re-roll your 'es/worktree-duplicate-paths' branch, could you
please squash this into the relevant patch (commit 71806ee9e8 (worktree: prune
linked worktree referencing main worktree path, 2020-06-08)).

Note that this is based on top of the 'pu' branch, and Junio has a fixup
patch (commit 4b01d684fe (SQUASH??? -Werror=main, 2020-06-08)) which also
changes this line of code (s/main/main_path/).

Thanks!

ATB,
Ramsay Jones

Thanks, I'll apply this change when I re-roll.

Indeed, I saw Junio's SQUASH and was planning on applying that, as well.
