Subject: [PATCH] scsi: mpt3sas: Increase event log buffer to support 24 port
 HBA's.
References: bsc#1086906,FATE#324923
Git-commit: 1537d1bfc58858f2e0a86c37977d92b05e0afa2e
Patch-mainline: v4.18-rc1

For 24 port HBA's events generated by IOC are more in certain cases and
the current circular buffer may be overwritten.Hence increased the event
log buffer to accommodate more events.
