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)

g_ether gadget: using random host ethernet address

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)
