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")
