bnxt_en: hide CONFIG_DETECT_HUNG_TASK specific code

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.
