pkeys: Remove easily triggered WARN

This easy-to-trigger warning shows up instantly when running Trinity on a kernel with CONFIG_X86_INTEL_MEMORY_PROTECTION_KEYS disabled. At most this should have been a printk, but the -EINVAL alone should be more than adequate indicator that something isn't available.
