[PATCH] btrfs: Remove unnecessary call to btrfs_mark_buffer_dirty()

[Zhen Ni <zhen.ni@easystack.cn>]

When btrfs_insert_empty_item() succeeds, the leaf has already been
marked dirty automatically through two mechanisms:

1) COW operations: btrfs_search_slot(cow=1)

2) setup_items_for_insert() → btrfs_mark_buffer_dirty(trans, leaf)

Therefore the explicit call in btrfs_insert_item() is redundant and can
be safely removed. This removes unnecessary code verbosity, reduces
overhead, and aligns with the cleanup done in commit 1ca4e15f41f2e
("btrfs: volumes: remove unnecessary calls to btrfs_mark_buffer_dirty()").
