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(). Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
