dtrace: ensure limit is enforced even when pcs is NULL

The dtrace_user_stacktrace() functions for x86_64 and sparc64 were
not handling the specified limit (st->limit correctly if the buffer
for PC values (st->pcs) was NULL.  This commit ensures that we
decrement the limit whenever we encounter a PC, whether it gets
stored or not.
