There are now many ways to trigger a devcoredump capture. So include a
reason message to say why it happened.

Also, add locking to avoid a races with double captures and free vs read.

v2: Change to spin_lock to mutex and a few other tweaks (review
feedback from Matthew Brost).
v3: Move mutex locks and add reclaim annotation (review feedback from
Matthew Brost).
v4: Fix typo - when adding lockdep specific code it helps to actually
have CONFIG_LOCKDEP enabled!
