Subject: [PATCH 4.19 102/109] KVM: selftests: Fix kvm_check_cap() assertion

From: Fuad Tabba <tabba@...gle.com>

[ Upstream commit d8ac05ea13d789d5491a5920d70a05659015441d ]

KVM_CHECK_EXTENSION ioctl can return any negative value on error,
and not necessarily -1. Change the assertion to reflect that.
