usb: gadget: f_hid: wake up readers on disable/unbind
Similar to how it is done in the write path.
Add a disabled flag to track the function state and use it to exit the read
loops to ensure no readers get stuck when the function is disabled/unbound,
protecting against corruption when the waitq and spinlocks are reinitialized
in hidg_bind().
