[V2,28/36] hrtimer: remove 'base' parameter from remove_timer() and __remove_timer()

clock 'base' can be obtained easily by doing timer->base and remove_timer()/
__remove_timer() never gets anything else than timer->base as its parameter.
Which means, these routines doesn't require this parameter. Remove it.
