The ASL Acquire operator (17.5.1 in ACPI 3.0 spec) is allowed to time out
and return True without acquiring the semaphore.  There's no indication in
the spec that this is an actual error, so this message should be
debug-only, as the message for successful acquisition is.

This used to be an ACPI_DEBUG_PRINT, but it was mis-classified as
ACPI_DB_ERROR rather than ACPI_DB_MUTEX, so it got swept up in Thomas'
recent patch to enable ACPI error messages even without CONFIG_ACPI_DEBUG.

This patch #if 0's the no longer used dlm_dump_lock_resources().

Since this makes dlmdebug.h empty, this patch also removes this header.

Additionally, the needlessly global dlm_is_node_recovered() is made
static.

If the previous master of the recovery lock dies, let calc_usage take it
down completely and let the caller completely redo the dlmlock() call.
Otherwise, there will never be an opportunity to re-master the lockres and
