[PATCH net 09/12] cxgb4: move DCB version extern to header file

[Rahul Lakkireddy]

Move the DCB version string array extern to header file.

Fixes following sparse warning:
cxgb4_dcb.c:13:12: warning: symbol 'dcb_ver_array' was not declared.
Should it be static?

Fixes: ebddd97afb89 ("cxgb4: add support to display DCB info")
