reiserfs: Initialize inode keys properly
reiserfs_read_locked_inode() didn't initialize key length properly. Use _make_cpu_key() macro for key initialization so that all key member are properly initialized. CC: stable@vger.kernel.org Reported-by: syzbot+d94d02749498bb7bab4b@syzkaller.appspotmail.com Signed-off-by: Jan Kara <jack@suse.cz>
