Subject: [PATCH net-next v2 2/8] netconsole: Make boolean comparison
 consistent

Convert the current state assignment to use explicit boolean conversion,
making the code more robust and easier to read. This change adds a
double-negation operator to ensure consistent boolean conversion as
suggested by Paolo[1].

This approach aligns with the existing pattern used in
sysdata_cpu_nr_enabled_show().
