xfs: move btree bulkload record initialization to ->get_record implementations
When we're performing a bulk load of a btree, move the code that
actually stores the btree record in the new btree block out of the
generic code and into the individual ->get_record implementations.
This is preparation for being able to store multiple records with a
single indirect call.
