wifi: ath12k: Fix a NULL pointer dereference in ath12k_mac_op_hw_scan()
In ath12k_mac_op_hw_scan(), the return value of kzalloc() is directly
used in memcpy(), which may lead to a NULL pointer dereference on
failure of kzalloc().
Fix this bug by adding a check of arg.extraie.ptr.
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
