worktree: fix resource leaks when branch creation fails
In the "add" subcommand, when `run_command()` fails while creating a new branch (line 948), the function returns -1 immediately without freeing the allocations made earlier: path (from prefix_filename at line 858), opt_track, branch_to_free, and new_branch_to_free. Redirect the error return through the existing cleanup block at the end of the function so all four allocations are properly freed. Pointed out by Coverity.
