[PATCH 6/6] btrfs: rename setup_extent_mapping in relocation code

[Johannes Thumshirn <johannes.thumshirn@wdc.com>]

In btrfs we have two functions called setup_extent_mapping, one in
the extent_map code and one in the relocation code. While both are private
to their respective implementation, this can still be confusing for the
reader.

So rename the version in relocation.c to setup_relocation_extent_mapping.
No functional change otherwise.
