Subject: [PATCH v2 2/6] KVM: VMX: Move PLE grow/shrink helpers above vmx_vcpu_load()

From: Sean Christopherson <[email-masked]>
Date: Tue, 21 May 2024 18:40:09 -0700

Move VMX's {grow,shrink}_ple_window() above vmx_vcpu_load() in preparation
of moving the sched_in logic, which handles shrinking the PLE window, into
vmx_vcpu_load().

No functional change intended.
