o extattrctl initattr, when pre-allocating store for extended attributes,

Browse Source 
computed a a chunksize that didn't include the extended attribute
  header.  This was a non-fatal error, in that it was just writing out
  zeros anyway, but did have the effect of not pre-allocating the
  right amount of disk space.  This fix calculates chunksize to include
  the attribute header.
