bnxt_en: Uninitialized variable in bnxt_tc_parse_actions()

Smatch warns that:

    drivers/net/ethernet/broadcom/bnxt/bnxt_tc.c:160 bnxt_tc_parse_actions()
    error: uninitialized symbol 'rc'.

"rc" is either uninitialized or set to zero here so we can just remove
the check.

Fixes: 8c95f773b4a3 ("bnxt_en: add support for Flower based vxlan encap/decap offload")
