Subject: [PATCH v2 3/7] KVM: PPC: Fix mmio length message

From: Fabiano Rosas <[email-masked]>
Date: Thu, 6 Jan 2022 17:03:00 -0300

We check against 'bytes' but print 'run->mmio.len' which at that point
has an old value.

e.g. 16-byte load:

before:
__kvmppc_handle_load: bad MMIO length: 8

now:
__kvmppc_handle_load: bad MMIO length: 16
