[PATCH weston] gl-renderer: remove unneeded cast

[Emil Velikov]

From: Emil Velikov <emil.velikov at collabora.com>

The variable num is of EGLint type.

The functions gl_renderer_query_dmabuf_* return bool as per the
interface. At the same time:
 - the caller does not check for it
 - the function happily writes over the output storage on error

Worth just dropping the return type, and documenting that on error
num_formats shall return 0?
