Kernel is doing correctly and requesting NVS data as expected, the
problem here is that linux-firmware claims that the example NVS data is
real calibration data (which it is not). Distros should not use that,
only developers for testing purposes. We should not courage users using
example calibration data.

The simple fix is to rename the NVS file in linux-firmware to something
like wl1251-nvs.bin.example, no need to workaround this in kernel. If
you send a patch to linux-firmware I'm happy to ack that.
