ALSA: aloop: Fix random zeros in capture data when using jiffies timer

commit 3e48940abee88b8dbbeeaf8a07e7b2b6be1271b3 upstream.

In loopback_jiffies_timer_pos_update(), we are getting jiffies twice.
First time for playback, second time for capture. Jiffies can be updated
between these two calls and if the capture jiffies is larger, extra zeros
will be filled in the capture buffer.

Change to get jiffies once and use it for both playback and capture.
