Updated the H5FS cache code to grab the correct tag and modified

the freespace test to use dxpls that have been tagged with
the H5AC__FREESPACE_TAG global tag instead of H5AC_ind_read_dxpl_id.
The library code now expects the owner of the free space manager
to tag it so the owner-less free space managers in the freespace
tag had to be tagged with *something* to avoid cache errors.
