libstagefright: unbreak hardware OMX on OMAP3

http://review.cyanogenmod.org/58070 has mistakenly reverted
http://review.cyanogenmod.org/44365 which broke hardware OMX
on OMAP3.

The fix for OMAP3 was just a logic change to prevent an
indefinate loop since the nIndex value was being overriden by
the OMX component. The code was modified to use a seprate control
value other than nIndex itself and doesnt pose any issues with
other platforms.
