Avoid null pointer dereference in cgit_print_diff().
When calling cgit_print_diff() with a bad new_rev and a NULL old_rev, checking for new_rev's parent commit will result in a null pointer dereference. Returning on an invalid commit before dereferencing fixes this. Spotted with clang-analyzer. Signed-off-by: Lukas Fleischer <cgit@cryptocrack.de> Signed-off-by: Lars Hjemli <hjemli@gmail.com>
