[0/2] Additional Diagnostic Buffer Query IOCTL

Message

* When a host trace buffer is released, applications never know for what
reason the buffer is released.
* Add new ioctl interface to pass more intelligent data to the
applications along with information like what causes or triggers the
buffer release. An Additional Query Command is issued before reading
the buffer and applications would also come to know whether the buffer
is released or not.

* Update the driver version.

  mpt3sas: Update driver version to 37.100.00.00

Applied to 5.12/scsi-staging, thanks!
