SCSI: mpt2sas: Excessive log info causes sas iounit page time out
commit be9e8cd75ce8d94ae4aab721fdcc337fa78a9090 upstream.
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.
