Subject: [PATCH] libxl: fix POLLHUP handling
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

The current code in bootloader_copyfail will error out on expected POLLHUPs
because of a missing "else" in the if clause.

The behaviour that triggers this bug has only been seen on FreeBSD so far.
