Subject: [PATCH] scsi: mpt3sas: Demote log level for trace buffer allocation to info

On a system with the controller below

    01:00.0 Serial Attached SCSI controller [0107]: Broadcom / LSI Fusion-MPT 12GSAS/PCIe Secure SAS38xx [1000:00e6]

Linux logs the error below:

    $ dmesg --level=err | grep mpt
    [    7.647675] mpt3sas_cm0: Trace buffer memory 2048 KB allocated

This state does not denote an error condition (and also no warning), so
demote the level from error to info.
