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

Fix logging of memory event type field of DRAM trace event.
For e.g. if value is 0x1 it will be reported 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: 9a2f6186db26 ("rasdaemon: Add support for the CXL dram events")
