[PATCH v3 2/6] swiotlb: Remove call to sme_active()

From: Thiago Jung Bauermann
Date: Wed Jul 17 2019 - 23:29:55 EST

sme_active() is an x86-specific function so it's better not to call it from
generic code.

There's no need to mention which memory encryption feature is active, so
just use a more generic message. Besides, other architectures will have
different names for similar technology.
