[PATCH 6.12 03/42] bnxt_en: hide CONFIG_DETECT_HUNG_TASK specific code

From: Arnd Bergmann <arnd@arndb.de>

commit 8ff6175139967cd17b2a62bca4b2de2559942b7e upstream.

The CONFIG_DEFAULT_HUNG_TASK_TIMEOUT setting is only available when the
hung task detection is enabled, otherwise the code now produces a build
failure:

drivers/net/ethernet/broadcom/bnxt/bnxt.c:10188:21: error: use of undeclared identifier 'CONFIG_DEFAULT_HUNG_TASK_TIMEOUT'
10188 | max_tmo_secs > CONFIG_DEFAULT_HUNG_TASK_TIMEOUT) {

Enclose this warning logic in an #ifdef to ensure this builds.
