Realip: fixed duplicate processing on redirects (ticket #1098).

Duplicate processing was possible if the address set by realip was
listed in set_realip_from, and there was an internal redirect so module
context was cleared.  This resulted in exactly the same address being set,
so this wasn't a problem before the $realip_remote_addr variable was
introduced, though now results in incorrect $realip_remote_addr being
picked.

Fix is to use ngx_http_realip_get_module_ctx() to look up module context
even if it was cleared.  Additionally, the order of checks was switched to
check the configuration first as it looks more effective.
