[SCSI] mpt2sas: Excessive log info causes sas iounit page time out
Inhibit 0x3117 loginfos - during cable pull, there are too many printks going to the syslog, this is have impact on how fast the interrupt routine can handle keeping up with command completions; this was the root cause to the config pages timeouts.
