Ilpo Järvinen f6c1a08e91 PCI: pciehp: Don't enable HPIE when resuming in poll mode ...

[ Upstream commit 527664f738afb6f2c58022cd35e63801e5dc7aec ]

PCIe hotplug can operate in poll mode without interrupt handlers using a
polling kthread only.  eb34da60ed ("PCI: pciehp: Disable hotplug
interrupt during suspend") failed to consider that and enables HPIE
(Hot-Plug Interrupt Enable) unconditionally when resuming the Port.

Only set HPIE if non-poll mode is in use. This makes
pcie_enable_interrupt() match how pcie_enable_notification() already
handles HPIE.
