[patch -resend] xen/privcmd: fix condition in privcmd_close()

[Dan Carpenter <dan.carpenter@oracle.com>]

The parenthesis are in the wrong place so the original code is
equivalent to:

	if (!xen_feature(0x1)) { ...
Or:
        if (!xen_feature(XENFEAT_writable_descriptor_tables)) { ...

Which obviously was not intended.

I sent this last November but it was never merged.
