rtc: Fix ioctl error path return
Bryan Henderson noticed that the "RTC: Fix rtc driver ioctl specific shortcutting" commit has a small bug: When an ioctl is called with an invalid command code and the clock driver does not have an "ioctl" method, the ioctl returns rc 0 instead of -ENOTTY. This patch fixes the issue. CC: Bryan Henderson <bryanh@giraffe-data.com> CC: Gabor Z.
