Module Name:    src
Committed By:   bouyer

Modified Files:
        src/sys/arch/xen/xen: xbdback_xenbus.c

Log Message:
When we stall the continuation waiting for the queued I/O to complete
in xbdback_co_cache_flush2(), we don't advance the req pointer. In this
case call xbdi_put() to compensate for the xbdi_get() that will be done again
in xbdback_co_main_loop().
Fix stalled xbdback detach that would stall the whole xenbus thread,
preventing new domU from be created.
