6.12-stable review patch. If anyone has any objections, please let me know.

From: Wentao Liang vulab@iscas.ac.cn
commit fb95897b8c60653805aa09daec575ca30983f768 upstream.
In xfs_dax_write_iomap_end(), directly return the result of xfs_reflink_cancel_cow_range() when !written, ensuring proper error propagation and improving code robustness.
