[PATCH] video: vpl: don't print only skipped vpl endpoints

The remote_vpl->ioctl is within a loop and every time an iteration is
skipped, a debug line is printed, but no debug line is printed when the
loop actually finds a remote_vpl to call its ioctl callback.

Make this debugging code more useful by adding a debug print in the
latter case.
