ALSA: pcm - Fix update of runtime->hw_ptr_interrupt

Browse Source 
The commit 13f040f9e5 made another
regression, the missing update of runtime->hw_ptr_interrupt.
Since this field is only checked in snd_pcmupdate__hw_ptr_interrupt(),
not in snd_pcm_update_hw_ptr(), it must be updated before the hw_ptr
change check.
