sparc64: move retry logic out of stickcmpr_set()

In some cases, stickcmpr_set() fails to ensure that %STICK_CMPR leads
%STICK before returning to the caller.  Rewriting the retry logic in C
trivially fixes the issue.  So move the retry logic out into a new
function, stick_rearm().

Issue discovered by miod@, fix tested by miod@.
