[PATCH] USB: net2280 updates

Net2280 patches to:

  - Make reset logic ensure endpoint toggle and halt bits only get cleared
    on endpoints other than ep0 to fix an extremely unlikely (but possible)
    state when a setup packet come in after we've checked the reset status
    but before calling ep_reset().

  - Avoid a disconnect hang by exchanging SUSPEND_IMMEDIATELY (intended for
    use when the 8051 is the PCI host) with SUSPEND_REQUEST_INTERRUPT to
    suspend the NET2280.

  - Make rmmod of gadget drivers trigger disconnect; earlier changes to
    reset logic broke this.
