msm: vidc: Report sufficient resources event as sufficient resources

Sufficient resources event was being reported as insufficient
resources event if smooth streaming mode is not set. This was
done earlier to save memory, since video memory was allocated
from carveout heap which was very limited. Now, video memory
is allocated from IOMMU heap, which is not a carveout and hence
takes more time for buffer allocation. It is therefore desired to
avoid port reconfig (free and reallocation of buffers) to reduce
startup latency.
