btrfs: delayed-inode: remove unnecessary call to btrfs_mark_buffer_dirty()

The call to btrfs_mark_buffer_dirty() at __btrfs_update_delayed_inode() 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.
