From: Colin Ian King <colin.k...@canonical.com>
Currently the variable err may be uninitialized if several of the if
statements are not executed in function nix_tx_vtag_decfg and a garbage
value in err is returned. Fix this by initialized ret at the start of
the function.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 9a946def264d ("octeontx2-af: Modify nix_vtag_cfg mailbox to support TX
VTAG entries")
