Krzysztof Chruściński e7d590568c kernel: timeout: Reduce number of sys_clock_elapsed calls 
sys_clock_elapsed requires access to system clock register interface
which is often slow. When new relative timeout is added sys_clock_elapsed()
is called once to calculate delta ticks and then if that triggers setting
new timeout sys_clock_elapsed() is called again. This call is redundant
since everything happens under spin lock so it is better to reuse value
returned by the first call.
