In trying to integrate the new gralloc_handle.h with the
drm_hwcomposer, I started seeing the following compilation
errors:

In file included from external/drm_hwcomposer/platformdrmgeneric.cpp:28:
external/libdrm/android/gralloc_handle.h:108:9: error: cannot initialize return 
object of type 'native_handle_t *' (aka 'native_handle *') with an lvalue of 
type 'struct gralloc_handle_t *'
        return handle;
               ^~~~~~
1 error generated.

This seems to be due to the gralloc_handle_create() definition
needs to return a native_handle_t * type, rather then a
gralloc_handle_t *, which is what the code actually returns.

After talking w/ Rob Herring, having the code return the
native handle should be the proper fix, so that is what
this patch changes.
