Subject[PATCH] ath11k: fix IRQ affinity warning on shutdown
Date
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.

Fixes: e94b07493da3 ("ath11k: Set IRQ affinity to CPU0 in case of one MSI vector")
