ring-buffer: move calculation of event length
The event length is calculated and passed in to rb_reserve_next_event
in two different locations. Having rb_reserve_next_event do the
calculations directly makes only one location to do the change and
causes the calculation to be inlined by gcc.
Before:

After:
text data bss dec hex filename

[ Impact: smaller more efficient code ]
