powerpc/powernv: Rate limit opal-elog read failure message

Browse source

Sometimes we can't read an error log from OPAL, and we print an error
message accordingly. But the OPAL userspace tools seem to like retrying a
lot, in which case we flood the kernel log with a lot of messages.

Change pr_err() to pr_err_ratelimited() to help with this.
