Colin Ian King ff3487b089 media: em28xx: Don't use ops->suspend if it is NULL
[ Upstream commit 51fa3b70d27342baf1ea8aaab3e96e5f4f26d5b2 ]

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")

Fixes: be7fd3c3a8c5 ("media: em28xx: Hauppauge DualHD second tuner functionality")
