iwlwifi: pcie: only use d0i3 in suspend/resume if system_pm is set to d0i3
[ Upstream commit e4c49c4937951de1cdbe35572ade40c948dec1e1 ]
We only need to handle d0i3 entry and exit during suspend resume if
system_pm is set to IWL_PLAT_PM_MODE_D0I3, otherwise d0i3 entry
failures will cause suspend to fail.
This fixes https://bugzilla.kernel.org/show_bug.cgi?id=194791
