arm64: psci: Avoid printing in cpu_psci_cpu_die()
[ Upstream commit 891deb87585017d526b67b59c15d38755b900fea ]
cpu_psci_cpu_die() is called in the context of the dying CPU, which
will no longer be online or tracked by RCU. It is therefore not generally
safe to call printk() if the PSCI "cpu off" request fails, so remove the
pr_crit() invocation.
