Fix timestamp in status in PCM direct plugins

PCM direct plugins didn't update the timestamp properly.
Now it always starts the slave PCM with MMAP tstamp_mode so that the
timestamp will be being updated.  When a client is set up as MMAP
tstamp_mode as well, simply copy this slave timestamp.  Otherwise
status callback calculates the current timestamp as usual.
