pcm: hw: do not reset tstamp_type in SND_PCM_APPEND mode

Browse source 
When the first client of plugins such as dshare open the hw device they set
a default tstamp_type in snd_pcm_direct_initialize_slave based on
tstamp_type from the config file. But when subsequent clients open the same
plugin the snd_pcm_hw_open_fd function clobbers this default.
