[PATCH] worktree: fix an 'using plain integer as NULL pointer' warning

Signed-off-by: Ramsay Jones <redacted>

Hi Duy,

If you need to re-roll your 'nd/worktree-move' branch, could you
please squash this into the relevant patch. (commit 62985f75c1
"worktree move: refuse to move worktrees with submodules", 08-01-2017).

[BTW, this is a sparse warning, just in case you were wondering!]

Thanks!

ATB,
Ramsay Jones
