linux: sysfs: use tracing_on as tracing_enabled is deprecated
tracing_enabled use in the kernel is being deprecated as per commit
6752ab4a9c30 [tracing: Deprecate tracing_enabled for tracing_on] in
the linux mainline kernel. tracing_enabled use will generate a warning
and may no longer function as expected, therefore move to use tracing_on.
