ALSA: cs4281: Send the PCM period elapsed notification properly 

As part of spin lock code cleanup using guard(), a new
variable (period_elapsed) was introduced. However this variable
is never set, causing period elapsed notification to be not sent.

Set the value of period_elapsed appropiately.

This issue was reported by static coverity analyzer.
