reiserfs: Initialize sec->length in reiserfs_security_init().
syzbot is reporting that sec->length is not initialized.
Since security_inode_init_security() returns 0 when initxattrs is provided
but call_int_hook(inode_init_security) returned -EOPNOTSUPP, control will
reach to "if (sec->length && ...) {" without initializing sec->length.
