ALSA: pcsp: Fix initialization with nopcm=1
When nopcm=1 is set, some initializations based on hrtimer resolution might be bogus because the driver checks the resolution only when nopcm=0. Simply get the resolution always at first for fixing the bug. Spotted by coverity CID 139740. Signed-off-by: Takashi Iwai <tiwai@suse.de>
