Subject: [PATCH] xfs: Add error handling for xfs_reflink_cancel_cow_range

In xfs_inactive(), xfs_reflink_cancel_cow_range() is called without error handling, risking unnoticed failures and inconsistent behavior compared to other parts of the code.

Fix this issue by adding an error handling for the xfs_reflink_cancel_cow_range(), improving code robustness.
