usb: gadget: f_midi: allow resetting index option
Unlike the other integral options supported by the MIDI gadget, index is
a signed integer and defaults to -1, which means "choose any sound card
index". The generic store routine parses input into a u32 which fails
to properly read -1 if an attempt is made to set the value to the
default.
Add a new macro block for signed values to fix this, and use the correct
format string for unsigned values.
