I just installed macchanger and run:
macchanger -s wlan0
Permanent MAC: 00:e0:4c:81:92:dc (Realtek Semiconductor Corp.)
Current   MAC: 00:e0:4c:81:92:dc (Realtek Semiconductor Corp.)

# macchanger -m 00:e0:4c:81:92:dc wlan0
Permanent MAC: 00:e0:4c:81:92:dc (Realtek Semiconductor Corp.)
Current   MAC: 00:e0:4c:81:92:dc (Realtek Semiconductor Corp.)
It's the same MAC!!

So after this what should I do with udev rules in
70-persistent-net.rules ?

Now the line is:
# USB device 0x:0x (rtl8192cu)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", \
ATTR{address}=="00:e0:4c:81:92:*", ATTR{dev_id}=="0x0", \
 ATTR{type}=="1", KERNEL=="wlan*", NAME="wlan0"
