msm: vidc: Increase minimum input buffer count for VP9 decode 



Increase minimum input buffer count for VP9 decode to 6,as
some vp9 clips which have superframes with more than 4 subframes
require more than 4 reference buffers to decode, and for some
clients output buffers are coupled with input buffers initially.
