Subject: [char-misc-next 2/2] mei: lower the log level for non-fatal failed messages

From: Vitaly Lubart <vitaly.lubart@...el.com>

Some non-fatal log messages should be logged at INFO log level
because failure to send/receive them is not breaking mei functionality
and may happen during legal firmware resets
