This seems to be the\n'num_stations' in 'struct ath11k' that did not get reset properly in\nthis case. In ath11k_mac_op_start(), it was indeed the only accounting var\nthat did not get reset so let's clear it too.\n\nThis avoids problems like those:\n\n\t[1248828.088023] WARNING: CPU: 0 PID: 12281 at
