Subject: [PATCH v2] mm, memory-failure: clarify error message

Some user who install SIGBUS handler that does longjmp out
therefore keeping the process alive is confused by the error
message
  "[188988.765862] Memory failure: 0x1840200: Killing
   cellsrv:33395 due to hardware memory corruption"
Slightly modify the error message to improve clarity.
