Xiaoguang Wu d7008408d0 DM USB: xHCI: fix issue: crash when plug device during UOS booting ...

This issue is result from reporting interrupt when the interrupt ability
of virtual xHCI is disabled.

As Event Ring State Machine showed in Figure 20 of xHCI spec, following
rules should be followed:
1 when RS bit of USBCMD register is zero, Event Ring should not be accessed;
2 when INTE bit of USBCMD register is zero, Interrupt should not be sent.
