Subject: [PATCH] ath10k: Drop WARN_ON()s that always trigger during system resume
Git-commit: 9e80ad37f6788ed52b89a3cfcd593e0aa69b216d
Patch-mainline: v5.1
References: bsc#1111666

ath10k_mac_vif_chan() always returns an error for the given vif
during system-wide resume which reliably triggers two WARN_ON()s
in ath10k_bss_info_changed() and they are not particularly
useful in that code path, so drop them.

Tested: QCA6174 hw3.2 PCI with WLAN.RM.2.0-00180-QCARMSWPZ-1
Tested: QCA6174 hw3.2 SDIO with WLAN.RMH.4.4.1-00007-QCARMSWP-1

Fixes: cd93b83ad927 ("ath10k: support for multicast rate control")
Fixes: f279294e9ee2 ("ath10k: add support for configuring management packet rate")
