[PATCH] wifi: ath11k: fix warning when unbinding

[Jose Ignacio Tornos Martinez]

Hello Rameshkumar,

The hardwre that I am using is QCNFA765, but I think it is something
related to ath11k driver and not related to some specific hardware.

I am running with the latest upstream kernel and I can reproduce it, so
I think it is not related with the problems that you comment.

Let me repeat this to try to clarify:

The easiest way to reproduce it is to run in a VM the default upstream
kernel (with this card using PCI passthrough), and since this is always
failing, just unbind the device (ath11k_pci).

The same problem was fixed by me for ath12k driver here ca68ce0d9f4b
("wifi: ath12k: fix warning when unbinding"), and I have seen the same
problem is also happening for ath11k driver.

Thanks

Best regards
José Ignacio
