scsi_target witness lock error

[Sean Bruno]

Alrighty, a little cleaner patch to allow sbp_targ.c to acutally work 
under RELENG_6.

Also and update with the witness error.  And the kernel config I am using:

Is scsi_target the only application that is making this kern env witness 
error appear?  I find it hard to believe that nothing else in the code 
base hits this type of problem?
