[PATCH] 9p: null terminate error strings for debug print

[Eric Van Hensbergen <ericvh@gmail.com>]

From: Eric Van Hensbergen <ericvh@strongmad.texas.9grid.us> - unquoted

We weren't properly NULL terminating protocol error strings for our
debug printk resulting in garbage being included in the output when debug
was enabled.
