Make delete method set via kern.cam.da.X.delete_method persistent.

This allows to set delete method via tunable, before device capabilities
are known.  Also allow ZERO method for devices not reporting LBP, if user
explicitly requests it -- it may be useful if storage supports compression
and WRITE SAME, but does not support UNMAP.
