Marco Felsch 0b276e470a media: coda: fix macroblocks count control usage 
Commit b2d3bef1aa ("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.
