wifi: ath12k: fix legacy peer association due to missing HT or 6 GHz capabilities

Currently SMPS configuration failed when the Information
Elements (IEs) did not contain HT or 6 GHz capabilities. This
caused legacy peer association to fail as legacy peers do not
have HT or 6 GHz capabilities. Fix this by not returning an
error when SMPS configuration fails due to the absence of HT
or 6 GHz capabilities.

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