Fix extra size argument in edata_init call in extent_alloc_dss

Browse source 
An extra 'size' argument was passed where 'slab' (false) should be,
shifting all subsequent arguments: slab got size (nonzero=true),
szind got false (0), and sn got SC_NSIZES instead of a proper serial
number from extent_sn_next(). Match the correct pattern used by the
gap edata_init call above.
