wifi: ath12k: fix driver initialization for WoW unsupported devices

Commit 4a3c212e ("wifi: ath12k: add basic WoW functionalities") broke
driver initialization, now mac registration is allowed only for devices that
advertise WMI_TLV_SERVICE_WOW, but QCN9274 doesn't support WoW and hence mac
registration is aborted and driver is de-initialized.

Allow mac registration to proceed without WoW Support for devices
that don't advertise WMI_TLV_SERVICE_WOW.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.0.1-00029-QCAHKSWPL_SILICONZ-1
