Kevin O'Connor ee56b14faa mcu: Fix endstop query timeout checking
Commit 0685802c changed the query endstop timeout to use host time
instead of the mcu clock.  However, it is possible for an endstop
homing request to be in the future which makes using the host time
inappropriate.  Revert back to using the mcu clock to determine when
to send an endstop query.
