usb:composite:fix Provide function data when addressing device with only one interface
This commit fixes problems with some non-standard requests send with
device address instead of interface address (bmRequestType.Receipent field).
This happens with dfu-util (debian version: 0.5), which address non standard
requests (like w_value=0x21 and bRequest=GET_DESCRIPTOR) to device.
Without this fix, the above request is STALLED, and hence causes dfu-util
to assume some standard configuration (packet size = 1024B instead of 4096B)
In turn it displays following errors:
Error obtaining DFU functional descriptor
Warning: Assuming DFU version 1.0
Warning: Transfer size can not be detected
...
Warning: Trying default transfer size 1024
This fix allows passing non-standard request to function setup code, where
it shall be handled.
Tested at: Trats (exynos4210)
Tested with:DFU and UMS gadgets
