sparc: leon: Fix a retry loop in leon_init_timers()
The original code causes a static checker warning because it has a
continue inside a do { } while (0); loop. In that context, a continue
and a break are equivalent. The intent was to go back to the start of
the loop so the continue was a bug.
I've added a retry label at the start and changed the continue to a goto
retry. Then I removed the do { } while (0) loop and pulled the code in
one indent level.
