During decoding setup stage for complex codecs like HEVC driver can
detect inconsistent values in controls or some other task, like
allocating memory, can fail.
Currently setup stage has no way of signalling error. Change return type
of setup callback to int and if returned value is not zero, skip
decoding and finish job immediately with error flag.
While currently there is only one place when setup can fail, it's
expected that there will be more such cases in the future, when HEVC
decoding is improved.
