BUG/MINOR: task: always reset a new tasklet's call date

Browse source 
The tasklet's call date was not reset, so if profiling was enabled while
some tasklets were in the run queue, their initial random value could be
used to preload a bogus initial latency value into the task profiling bin.
Let's just zero the initial value.

This should be backported to 2.4 as it was brought with initial commit
b2285de04 ("MINOR: tasks: also compute the tasklet latency when DEBUG_TASK
is set"). The impact is very low though.
