[SRU][F][PATCH v2 1/5] x86/kvm: Fix pr_info() for async PF setup/teardown

[Andrea Righi]

From: Vitaly Kuznetsov <vkuznets at redhat.com>

BugLink: https://bugs.launchpad.net/bugs/1920944

'pr_fmt' already has 'kvm-guest: ' so 'KVM' prefix is redundant.
"Unregister pv shared memory" is very ambiguous, it's hard to
say which particular PV feature it relates to.
