This is three essential bug fixes for various SCSI parts. The only affected
users are SCSI multi-path via device handler (basically all the enterprise)
and mvsas users. The dh bugs are an async entanglement in boot resulting in a
serious WARN_ON trip and a use after free on remove leading to a crash with
strict memory accounting. The mvsas bug manifests as a null deref oops but
only on abort sequences; however, these can commonly occur with SATA attached
devices, hence the fix.
