9p: strlen() doesn't count the terminator

commit 5c4bfa17f3ec46becec4b23d12323f7605ebd696 upstream.

This is an off by one bug because strlen() doesn't count the NULL
terminator.  We strcpy() addr into a fixed length array of size
UNIX_PATH_MAX later on.

The addr variable is the name of the device being mounted.
