A few gadgets provide a harcoded string in case the module parameter was
not used.
If nothing is provided then composite_bind() creates a string which is
based on the kernel version and UDC's name. Some gadget create the exact
same sting.
This patch moves the creation of the string into
composite_default_mfr().
