[PATCH 6/7] ata: libata-eh: Host support has nothing to do with disabling DIPM

[Niklas Cassel <cassel@kernel.org>]

It makes sense to take host support for DIPM into account when
enabling DIPM, however, it makes zero sense to take host support
into account when disabling DIPM.

If the host does not support DIPM, that is a very good reason to
not keep the feature enabled on the device side.
