Fix an address arithmetic problem in software codec

In software codec, there is such code like above[6-i], while i is an unsigned int.
If i equals to 7, above[6-i] will try to access *(above + 0xFFFFFFFFU) thus causes crash.

Correctly handle unsupported OMX color format

MediaServer was caught in an infinite loop at OMX::getParameter.

OMX::getParameter returns status_t, using OMX_ErrorNoMore to loop
until the index passes beyond the last supported format
will not work since this function only returns ERROR_UNSUPPORTED.
