wifi: qtnfmac: use always-managed version of pcim_intx()

pci_intx() is a hybrid function which can sometimes be managed through
devres. To remove this hybrid nature from pci_intx(), it is necessary to
port users to either an always-managed or a never-managed version.

qtnfmac enables its PCI device with pcim_enable_device(). Thus, it needs
the always-managed version.

Replace pci_intx() with pcim_intx().
