Luis Henriques 8f16da1dcd tracing: Fix tracing_stat return values in error handling paths 
[ Upstream commit afccc00f75 ]

tracing_stat_init() was always returning '0', even on the error paths.  It
now returns -ENODEV if tracing_init_dentry() fails or -ENOMEM if it fails
to created the 'trace_stat' debugfs directory.

Fixes: ed6f1c996b ("tracing: Check return value of tracing_init_dentry()")
