SCSI fixes on 20161111

Browse source 
The megaraid_sas patch in here fixes a major regression in the last
 fix set that made all megaraid_sas cards unusable.  It turns out
 no-one had actually tested such an "obvious" fix, sigh.  The fix for
 the fix has been tested ...
 
 The next most serious is the vmw_pvscsi abort problem which basically
 means that aborts don't work on the vmware paravirt devices and error
 handling always escalates to reset.
 
 The rest are an assortment of missed reference counting in certain
 paths and corner case bugs that show up on some architectures.
