Staging: lustre: Use setup_timer to combine initialization

The function setup_timer combines the initialization of a timer with the
initialization of the timer's function and data fields.

So, this patch combines the multiline code for timer initialization using the function
setup_timer. This issue is identified via coccinelle script.
