[PATCH RFC 2/4] wifi: ath12k: cleanup unneeded labels

[Kalle Valo <kvalo@kernel.org>]

From: Kalle Valo <quic_kvalo@quicinc.com>

After removing the conf_mutex in the previous patch there are no unnecessary
labels in mac.c. Sparse also warns one instance of it:

drivers/net/wireless/ath/ath12k/mac.c:6635:1: warning: statement expected after label

Remove the labels and instead use directly return.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
