Anton Vorontsov 1f15a506f3 USB: fsl_usb2_udc: Report disconnect before unbinding 
Gadgets disable endpoints in their disconnect callbacks, so
we must call disconnect before unbinding.

The patch fixes following badness:

root@b1:~# insmod fsl_usb2_udc.ko
Freescale High-Speed USB SOC Device Controller driver (Apr 20, 2007)
root@b1:~# insmod g_ether.ko
g_ether gadget: using random self ethernet address
g_ether gadget: using random host ethernet address
usb0: MAC 26:07:ba:c0:44:33
usb0: HOST MAC 96:81:0c:05:4d:e3
g_ether gadget: Ethernet Gadget, version: Memorial Day 2008
g_ether gadget: g_ether ready
fsl-usb2-udc: bind to driver g_ether
g_ether gadget: high speed config #1: CDC Ethernet (ECM)
root@b1:~# rmmod g_ether.ko
