tracing: fix a typo in tracing_cpumask_write()
It's tracing_cpumask_new that should be kfree()ed.
This causes tracing_cpumask to be freed due to the typo:
# echo z > tracing_cpumask
bash: echo: write error: Invalid argument
And subsequent reads/writes to tracing_cpuamsk will access this
already-freed tracing_cpumask, thus may lead to crash.
[ Impact: fix leak and crash when writing invalid val to tracing_cpumask ]
