    Now the call chain
     cpts_find_ts()
      |- cpts_fifo_read(cpts, CPTS_EV_PUSH)
    
    will stop reading CPTS FIFO if PUSH event is found. But this is not
    expected and CPTS FIFI should be completely drained here. This is most
    probably copy-paste error and it has no negative impact as CPTS_EV_PUSH
    should not be present in FIFO without TS_PUSH request and
    cpts_systim_read() and cpts_find_ts() synchronized by spin_lock.
    
    Correct above by calling cpts_fifo_read() with -1 parameter, so it will
    read all CPTS event from FIFO.
