drivers: wifi: Fix throughput degradation in BLE

The anomaly 43 workaround introduces extra delay due to waiting for QSPI
ready and causes BLE throughput drops as Wi-Fi driver is waiting and
halting the APP.

But this anomaly is only for XIP, so, can be disabled when using QSPI
for Wi-Fi comms.

Fixes SHEL-1633.
