On some platforms, the VBus will drop after suspending is done, hence
a disconnect and re-connect for device connected before suspending will
be triggered in DM. But during the stress test, when the free memory is
limited to very low level, and put huge workload to SOS, under certain
possibility, the DM will receive re-connect event first and disconnect
event later, this behavior will result of failing to emulate USB device
to UOS.
The reason is due to a timing issue from libusb. Before we could upstream
fixing patch to libusb or find some other better solution, this workaround
patch will be used to avoid errors happen.

The thread function usb_dev_sys_thread is the source of libusb events,
which is also the basis of USB/xHCI emulation. During S3 process,
function libusb_handle_events_timeout may fail and return -1, which
could result of exit of the thread (BTW, this failure is resulted from
USB native reseting behavior during S3). Under this situation, the emulation
of USB/xHCI could never continue.
This patch fix this issue by continuing to call libusb_handle_events_timeout
even it reture -1. The return value will be finally ok after S3 process is
completed.
This patch will continue poll after failure and hence fix this issue.
