Avoid unused variable errors in aesgcm_non12iv_test

[padelsbach]

Description

Currently blocking wolfHSM CI with the error below:

cc  -std=c90 -Werror -Wall -Wextra -ffunction-sections -fdata-sections -ggdb -g3 -fsanitize=address -D_POSIX_C_SOURCE=200809L -DWOLFHSM_CFG -DWOLFSSL_USER_SETTINGS -DWOLFHSM_CFG_DEBUG -DWOLFHSM_CFG_DEBUG_VERBOSE -DWC_USE_DEVID=0x5748534D -DWOLFHSM_CFG_ENABLE_AUTHENTICATION -I. -I./config -I./../ -I../../../wolfssl -I../../../ -I../../..//port/posix -I../../..//examples/demo/client -c -o Build/wh_demo_client_wctest.o ../../..//examples/demo/client/wh_demo_client_wctest.c

cc1: all warnings being treated as errors

Note: wolfHSM tests define BENCH_EMBEDDED which means BENCH_AESGCM_LARGE is undefined and dec is not used.
