Subject: ocfs2: fix panic on kfree(xattr->name)

Commit 9548906b 'xattr: Constify ->name member of "struct xattr".' missed that
ocfs2 is calling kfree(xattr->name). As a result, kernel panic occurs upon
calling kfree(xattr->name) because xattr->name refers static constant names.
This patch removes kfree(xattr->name) from ocfs2_mknod() and ocfs2_symlink().
