Subject: [PATCH] octeontx2-af: fix uninitialized variable

From: Tom Rix <trix@...hat.com>

Building with clang 13 reports this error
rvu_nix.c:4600:7: error: variable 'val' is used uninitialized whenever
  'if' condition is false
                if (!is_rvu_otx2(rvu))
                    ^~~~~~~~~~~~~~~~~

So initialize val.

Fixes: 4b5a3ab17c6c ("octeontx2-af: Hardware configuration for inline IPsec")
