[PATCH] crypto: aes-ni - Don't print message with KERN_ERR on old system

[Roland Dreier]

When the aes-intel module is loaded on a system that does not have the
AES instructions, it prints

    Intel AES-NI instructions are not detected.

at level KERN_ERR.  Since aes-intel is aliased to "aes" it will be tried
whenever anything uses AES and spam the console.  This doesn't match
existing practice for how to handle "no hardware" when initializing a
module, so downgrade the message to KERN_INFO.
