Justin Stitt 220dd227ca sfc: replace deprecated strncpy with strscpy 
strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.

`desc` is expected to be NUL-terminated as evident by the manual
NUL-byte assignment. Moreover, NUL-padding does not seem to be
necessary.

The only caller of efx_mcdi_nvram_metadata() is
efx_devlink_info_nvram_partition() which provides a NULL for `desc`:
|       rc = efx_mcdi_nvram_metadata(efx, partition_type, NULL, version, NULL, 0);

Due to this, I am not sure this code is even reached but we should still
favor something other than strncpy.

Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.
