[PATCH 04/20] btrfs: block-group: remove unnecessary calls to btrfs_mark_buffer_dirty()

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

We have several places explicitly calling btrfs_mark_buffer_dirty() but
that is not necessarily since the target leaf came from a path that was
obtained for a btree search function that modifies the btree, something
like btrfs_insert_empty_item() or anything else that ends up calling
btrfs_search_slot() with a value of 1 for its 'cow' argument.

These just make the code more verbose, confusing and add a little extra
overhead and well as increase the module's text size, so remove them.
