Subject: [PATCH 5.10 421/575] powerpc: Rename is_kvm_guest() to check_kvm_guest()

From: Srikar Dronamraju <srikar@...ux.vnet.ibm.com>

[ Upstream commit 16520a858a995742c2d2248e86a6026bd0316562 ]

We want to reuse the is_kvm_guest() name in a subsequent patch but
with a new body. Hence rename is_kvm_guest() to check_kvm_guest(). No
additional changes.
