swscale: fix NULL checking in sws_alloc_context()
...
sws_getCachedContext() and sws_getContext() expect sws_alloc_context()
to return NULL when out of memory, as follows.
if (!(context = sws_alloc_context()))
return NULL;
This patch fixes sws_alloc_context() to return NULL in that case.

Otherwise during scaling it will try to interpret input in the wrong way and
that leads to the test results disagreeing on different platforms and with
different optimizations.
