[media] media_entity: remove gfp_flags argument

Browse Source 
We should not be creating device nodes at IRQ contexts. So,
the only flags we'll be using will be GFP_KERNEL. Let's
remove the gfp_flags, in order to make the interface simpler.

If we ever need it, it would be easy to revert those changes.

While here, remove an extra blank line.
