ALSA: timer: fix nsec/sec initialization confusion 

GCC reports a warning with W=1:

sound/core/timer.c: In function ‘snd_timer_user_read’:
sound/core/timer.c:2219:19: warning: initialized field overwritten
[-Woverride-init]
 2219 |     .tstamp_sec = tread->tstamp_nsec,
      |                   ^~~~~
sound/core/timer.c:2219:19: note: (near initialization for
‘(anonymous).tstamp_sec’)

Assigning nsec values to sec fields is problematic in general, even
more so when the initial goal was to survive the 2030 timer
armageddon.

Fix by using the proper field in the initialization
