 SCSI fixes on 20131028
 
 This is a set of four patches that revert functionality introduced in the
 merge window to sg.  The locking changes turned out to introduce this bug:
 
     [  205.372901] [ BUG: lock held when returning to user space! ]
 [...]
     [  205.373285]  #0:  (&sdp->o_sem){.+.+..}, at: [<ffffffff8161e650>] sg_open+0x3a0/0x4d0
 
 The fix is large, so at this late stage we'd like to revert the functionality
 and start again in the next merge window.
