[PATCH] mtd: sm_ftl: replace strncpy with memcpy

[Rahul Kumar]

Replace strncpy with memcpy in sm_attr_show and explicitly add a NUL
terminator after the copy. This aligns with current kernel best practices
as strncpy is deprecated for such use, as explained in
Documentation/process/deprecated.rst. This change does not alter the
functionality or introduce any behavioral changes.
