Remove handling of KVM_REQ_APICV_UPDATE from svm_vcpu_unblocking(), it's
no longer needed as it was made obsolete by commit df7e4827c5 ("KVM:
SVM: call avic_vcpu_load/avic_vcpu_put when enabling/disabling AVIC").
Prior to that commit, the manual check was necessary to ensure the AVIC
stuff was updated by avic_set_running() when a request to enable APICv
became pending while the vCPU was blocking, as the request handling
itself would not do the update. But, as evidenced by the commit, that
logic was flawed and subject to various races.
Now that svm_refresh_apicv_exec_ctrl() does avic_vcpu_load/put() in
response to an APICv status change, drop the manual check in the
unblocking path.
