[PATCH] xfs: Propagate errors from xfs_reflink_cancel_cow_range in xfs_dax_write_iomap_end

[Wentao Liang]

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.

Fixes: ea6c49b784f0 ("xfs: support CoW in fsdax mode")
