ALSA: firewire-lib: fix uninitialized local variable

Browse Source 
The function local variable, curr_cycle_time is declared without
initialization. When tracepoints event is not probed, it looks to be
used as is. This commit fixes it. Fortunately, the value of local variable
is not used unless the event is probed, thus this commit is for better
coding.
