This is a no-op that bumps PORTREVISION so quarterly is in sync and
future MFH works cleanly.

devel/pecl-ev: fix patch, port was out of sync with quarterly

Somehow head/devel/pecl-ev and the quarterly version became out of sync.
The quarterly one already had a patch for libev/ev.c that covered the
intended change and more. I can't reproduce a build issue with 10.1 or
9.3, so I'm attempting to re-sync the ports at PORTREVISION=2 and then
we can approach any leftover issues that arise. We should then be able
to do a clean MFH as well.
