[PATCH 08/12] ath11k: Avoid "No VIF found" warning message

[Jouni Malinen]

From: Karthikeyan Periyasamy <periyasa at codeaurora.org>

Facing below warning prints when we do wifi down in multiple VAPs scenario.

warning print:

ath11k c000000.wifi: No VIF found for vdev 2
...
ath11k c000000.wifi: No VIF found for vdev 0

In ath11k_mac_get_arvif_by_vdev_id(), we iterate all the radio to get the
arvif for the requested vdev_id through ath11k_mac_get_arvif().
ath11k_mac_get_arvif() throws a warning message if the given vdev_id is
not found in the given radio. So to avoid the warning message, add
the allocated_vdev_map cross check against the given vdev_id before using
ath11k_mac_get_arvif() to ensure that vdev_id is allocated in the
given radio.
