cxl/events: Test CME counter expiry with equality, not bitwise AND

The Memory Event Type field in the General Media and DRAM event records
is an enumeration, not a bitmask. The validity checks for the advanced
programmable CME counter expiration event (05h) test the field with a
bitwise AND, so types 01h, 03h, 04h and 06h match it as well.

A device reporting one of those types trips WARN_ON_ONCE once the
general media or DRAM tracepoint is enabled, which is the case anywhere
rasdaemon collects CXL events. Under panic_on_warn=1 that kills the
machine.

Compare the type field for equality instead. Type 05h records that do
violate the spec conditions still warn.
