[PATCH 06/20] btrfs: dev-replace: remove unnecessary call to btrfs_mark_buffer_dirty()

[fdmanana@kernel.org]

From: Filipe Manana <fdmanana@suse.com>

The call to btrfs_mark_buffer_dirty() at btrfs_run_dev_replace() is not
necessary as we have a path setup for writing with btrfs_search_slot()
having a 'cow' argument set to 1.

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