btrfs: factor init_extent_buffer from __alloc_extent_buffer

Browse source

In preparation for preallocating extent_buffer data, factor eb
initialization away from specifically allocating it. This allows us to
allocate the eb, bfs, folios, etc. together in the main search_slot code
paths, but still share initialization code with the dummy/test/clone
allocation paths.
