USB: fsl_qe_udc: Fix disconnects reporting during bus reset

Freescale QE UDC controllers can't report the "port change" states,
so the only way to handle disconnects is to process bus reset
interrupts. The bus reset can take some time, that is, few irqs.
Gadgets may print the disconnection events, and this causes few
repetitive messages in the kernel log.

This patch fixes the issue by using the usb_state machine, if the
usb controller has been already reset, just quit the reset irq
early.
