ALSA: hda-intel - fix wallclk variable update and condition
This patch fixes thinko introduced in "last minutes" before commiting of the last wallclk patch. It also fixes the condition checking if the first period after last wallclk update is processed. There is a little rounding error in period_wallclk. Signed-off-by: Jaroslav Kysela <perex@perex.cz>
