mm/memory-failure: trace: change memory_failure_event to ras subsystem

Browse Source 
Commit 97f0b13452 ("tracing: add trace event for memory-failure")
introduced memory_failure_event in ras subsystem.  commit 31807483d3
("mm/memory-failure: remove the selection of RAS") changed
memory_failure_event to memory_failure subsystem.  This breaks the
backward compatibility, some user programs rely on it.

Change memory_failure_event to ras subsystem to keep backward
compatibility.
