[PATCH net-next v1] NFC: s3fwrn5: Replace strcpy() with strscpy()

[tomasz . unger]

From: Tomasz Unger <tomasz.unger@xxxxxxxx>

Replace strcpy() with strscpy() which limits the copy to the size of
the destination buffer. Since fw_info->fw_name is an array, the
two-argument variant of strscpy() is used - the compiler deduces
the buffer size automatically.

This is a defensive cleanup replacing the deprecated strcpy()
with the preferred strscpy().
