ath11k: fix IRQ affinity warning on shutdown
Make sure to clear the IRQ affinity hint also on shutdown to avoid
triggering a WARN_ON_ONCE() in __free_irq() when stopping MHI while
using a single MSI vector.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3
Fixes: e94b07493da3 ("ath11k: Set IRQ affinity to CPU0 in case of one MSI vector")
