Jason Andryuk 9288e803e6 xen-hvm: Allow disabling buffer_io_timer 
commit f37f29d314 "xen: slightly simplify bufioreq handling" hard
coded setting req.count = 1 during initial field setup before the main
loop.  This missed a subtlety that an early exit from the loop when
there are no ioreqs to process, would have req.count == 0 for the return
value.  handle_buffered_io() would then remove state->buffered_io_timer.
Instead handle_buffered_iopage() is basically always returning true and
handle_buffered_io() always re-setting the timer.

Restore the disabling of the timer by introducing a new handled_ioreq
boolean and use as the return value.  The named variable will more
clearly show the intent of the code.
