xhci: use correct flags for spin_lock_irqrestore() when setting port power
commit a6ff6cbf1fab ("usb: xhci: Add helper function xhci_set_power_on().")
created a helper to control port power that needs to be called with
xhci->lock held and interrupts disabled.
It released the lock with spin_unlock_irqrestore using a new zero flag
variable instead of the original flag from spin_lock_irqsave.
This regression triggered a static checker warning about bogus flags, and
a null pointer dereference on armada-385.
Fix it by passing a pointer to the correct flags and using it instead
