iwlwifi: make sure d3_suspend/resume ops exist
We added calls to d3_suspend/resume trans ops during the
suspend/resume flow.
However, the wrapper code didn't verify the trans ops were
actually defined, resulting in panic when they were not
(such as in the case of sdio trans)
Fixes: 6dfb36c89dc2 ("iwlwifi: call d3_suspend/resume in d0i3 case as well")
