Fix USB interface addressing for control packet
Async events doesn't work for composite devices, when MTP interface
is not located as the first one in the descriptors. Control transfers,
by default are addressed to interface 0 but should be addressed to
actual interface. For this purpose wIndex field should contain
address of target interface.
