No version of vfe_disable() currently returns nor has ever as near as I
can discern ever returned a meaningful error code.

Convert from the unused int return to void.

Fixes: 633b388f85c5 ("media: camss: Refactor VFE HW version support")

Up the chain, vfe_reset can fail but the error isn't propagated
