Steven Rostedt (Red Hat) 14a5ae40f0 tracing: Use IS_ERR() check for return value of tracing_init_dentry() ...

tracing_init_dentry() will soon return NULL as a valid pointer for the
top level tracing directroy. NULL can not be used as an error value.
Instead, switch to ERR_PTR() and check the return status with
IS_ERR().
