net: libwx: fix device bus LAN ID
commit a04ea57aae375bdda1cb57034d8bcbb351e1f973 upstream.
The device bus LAN ID was obtained from PCI_FUNC(), but when a PF
port is passthrough to a virtual machine, the function number may not
match the actual port index on the device. This could cause the driver
to perform operations such as LAN reset on the wrong port.
Fix this by reading the LAN ID from port status register.
