From: Shiju Jose <shiju.jose@huawei.com>

CXL spec rev 3.0 section 8.2.9.2.1.2 defines the DRAM Event Record.

Fix decoding of memory event type in the CXL DRAM error table in RAS
SQLite database.
For e.g. if value is 0x1 it will be logged as an Invalid Address
(General Media Event Record - Memory Event Type) instead of Scrub Media
ECC Error (DRAM Event Record - Memory Event Type) and so on.

Fixes: c38c14afc5d7 ("rasdaemon: ras-mc-ctl: Add support for CXL DRAM trace events")
