drvs/intel/wifi/wifi: Fix regression
Fix regression introduced by Change-Id:
I8b5c916f1a04742507dc1ecc9a20c19d3822b18c
In case the regular PCI path is taken, there're no chip_ops and the code
will segfault.
The bug was covered by other bugs that caused this code to never execute.
Don't assume the chip_operations path was taken and instead define the
device name, to be used all over the code.
Tested on Lenovo T430 and wifi card 8086:0085.
