Colin Ian King 51fa3b70d2 media: em28xx: Don't use ops->suspend if it is NULL

The call to ops->suspend for the dev->dev_next case can currently
trigger a call on a null function pointer if ops->suspend is null.
Skip over the use of function ops->suspend if it is null.

Addresses-Coverity: ("Dereference after null check")
