When we determine that the "device" argument represents a path to a char
device, we call phc_open() and then we attempt to see, if the device
real path starts with "/dev/ptp", what number comes afterwards. If that
fails, we should close the char device we've just opened.
Fixes: 380d023abb1f ("posix_clock_open: derive PHC index from device name if
possible")
