xfs: Replace strncpy with memcpy

[ Upstream commit 33ddc796ecbd50cd6211aa9e9eddbf4567038b49 ]

The changes modernizes the code by aligning it with current kernel best
practices. It improves code clarity and consistency, as strncpy is deprecated
as explained in Documentation/process/deprecated.rst. This change does
not alter the functionality or introduce any behavioral changes.
