wifi: ath12k: change to use dynamic memory for channel list of scan
Currently there are about 60 channels for 6 GHz, then the size of
chan_list in struct scan_req_params which is 40 is not enough to
fill all the channel list of 6 GHz.
Use dynamic memory to save the channel list of scan.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
