sound: usb: Map interface context information to interface number
Driver is dynamically allocating memory based on bNumInterface from
device configuration descriptor and stores interface context
information using bInterfaceNum. Device can advertise
bInterfaceNum >= bNumInterface which results into out of bound memory
access. Hence create a mapping between interface context index and
interface number. Use this mapping to find unused context index or
load the context information of an interface.
