[LU-3057] Hang at sanity test_56x and test_56w

The root cause of this problem is that ll_setattr is called directly in ioctl ll_swap_layouts(). It should have been called with inode mutex held.

        if (llss->ia2.ia_valid != 0)
                rc = ll_setattr(file1->f_dentry, &llss->ia2);

        if (llss->ia1.ia_valid != 0)
                rc1 = ll_setattr(file2->f_dentry, &llss->ia1);
