The comment for CONFIG_BOOTPARAM_HUNG_TASK_PANIC says:
Say N if unsure.
but since commit 9544f9e6947f ("hung_task: panic when there are more than N
hung tasks at the same time"), N is not a valid value for the option,
leading to a warning at build time:
.config:11736:warning: symbol value 'n' invalid for BOOTPARAM_HUNG_TASK_PANIC
as well as an error when given to menuconfig.
Fix the comment to say '0' instead of 'N'.
Fixes: 9544f9e6947f ("hung_task: panic when there are more than N hung tasks at the same time")
