The function pm8001_pci_resume() only calls pm8001_request_irq() without
calling pm8001_setup_irq(). This causes the IRQ allocation to fail, which
leads all drives being removed from the system.

Fix this issue by integrating the code for pm8001_setup_irq() directly
inside pm8001_request_irq() so that MSI-X setup is performed both during
normal initialization and resume operations.
