usb: xhci: Reduce command reset handshake timeout 



Command reset handshake is currently perfomed with local irq
disabled and spinlock held for 10 sec timeout. In this case xHC
becomes unresponsive and results into watchdog bark.
Hence reduce timeout value from 10 sec to 1 sec to initiate
recovery faster.
