[PATCH] media: coda: fix comparision of decoded frames' indexes

[Martin Kepplinger]

At this point the driver looks the currently decoded frame's index
and compares is to VPU-specific state values. Directly before this
if and else statements the indexes are read (index for decoded and
for displayed frame).

Now what is saved in ctx->display_idx is an older value at this point!
During these index checks, the current values apply, so fix this by
taking display_idx instead of ctx->display_idx.

ctx->display_idx is updated later in the same function.

Please review this thoroughly, but in case I am wrong here, this is
at least very strange to read and *should* be accompanied with a
comment about what's going on with that index value!

I don't think it matter that much here because at least playing h264
worked before and works with this change, but I've tested it anyways.

thanks
