If btmtk_usb_reg_read() gets a "short" read from a device, it will accidentally treat that as a "real" read and populate the returned value with some unknown and probably totally invalid data. Fix this logic error up by calling usb_control_msg_recv() which guarantees a "full" read happens, and then simplify the error checking for when btmtk_usb_reg_read() is called (it's really just btmtk_usb_id_get() that calls btmtk_usb_reg_read(), so fix up those return sites.
