ALSA: seq: Fix time account regression
The recent rewrite of the sequencer time accounting using timespec64
in the commit [3915bf294652: ALSA: seq_timer: use monotonic times
internally] introduced a bad regression. Namely, the time reported
back doesn't increase but goes back and forth.
The culprit was obvious: the delta is stored to the result (cur_time =
delta), instead of adding the delta (cur_time += delta)!
Let's fix it.
Fixes: 3915bf294652 ('ALSA: seq_timer: use monotonic times internally')
