usb: urgent fixes for v3.10 merge window

Here are some late urgent fixes for v3.10 merge window.

All of these errors were introduced by recent commits
which are in linux-next.

f_obex, multi and cdc2 gadget drivers have learned to
return a proper error code when something goes wrong.

usb_bind_phy() was mistakenly placed into .init.text
section which caused Section mismatch warnings and undefined
reference compile errors.

f_source_sink had a copy-paste error which is now corrected.

g_zero got a memory leak plugged.

Two defconfigs got fixed to enable the newly introduced
CONFIG_USB_PHY.
