bnxt_en: Refactor bnxt_dl_info_get().

Browse Source 
Add a new function bnxt_dl_info_put() to simplify the code, as there
are more stored firmware version fields to be added in the next patch.

Also, rename fw_ver variable name to ncsi_ver for better naming while
copying to devlink info_get cb.

v2:
Ensure active_pkg_name string is NULL terminated when copied to
devlink.

Return directly from the last call to bnxt_dl_info_put().
