x86/MSI: drop bogus NULL check from pci_restore_msi_state()

Commit 372900faf8 ("x86/MSI-X: reduce fiddling with control register
during restore") introduced de-references of pdev before it gets
checked against NULL. Instead of deferring the de-references, drop
the pointless check - both call sites do that check already.
