media: coda: fix macroblocks count control usageHEADmaster
Commit b2d3bef1aa78 ("media: coda: Add a V4L2 user for control error macroblocks count") add the control for the decoder devices. But during streamon() this ioctl gets called for all (encoder and decoder) devices and on encoder devices this causes a null pointer exception. Fix this by setting the control only if it is really accessible.
