media: em28xx: Don't use ops->resume if NULL
Changeset be7fd3c3a8c5 ("media: em28xx: Hauppauge DualHD
second tuner functionality") introduced a potential NULL pointer
dereference, as pointed by Coverity:
CID 1434731 (#1 of 1): Dereference after null check (FORWARD_NULL)16. var_deref_op: Dereferencing null pointer ops->resume.
var_compare_op: Comparing ops->resume to null implies that ops->resume might be null.
1174 if (ops->resume)
1175 ops->resume(dev);
1176 if (dev->dev_next)
1177 ops->resume(dev->dev_next);
Fixes: be7fd3c3a8c5 ("media: em28xx: Hauppauge DualHD second tuner functionality")
