qlcnic: fix memory leak in qlcnic_blink_led.
o Memory allocated in ETHTOOL_ACTIVE mode, is not getting freed. So, in ETHTOOL_ID_INACTIVE mode, return after freeing allocated memory. o Using set bit instead of blink_down field, as it is also required in internal Loopback test and etc. Signed-off-by: Sucheta Chakraborty <sucheta.chakraborty@qlogic.com> Signed-off-by: Amit Kumar Salecha <amit.salecha@qlogic.com> Signed-off-by: David S.
