When the inode is zero, get_pid_from_inode will match it with invalid
file descriptors. It will therefor return pid 1 (init), because it is
the first to match with inode zero. This patch checks the inode given
and returns a zero pid if the inode is also zero.
Obviously I'd fix the comment before applying.
