[PATCH] drivers: ras: cec: return value check of `d`

[Ruliang Lin]

Smatch complains that:
create_debugfs_nodes() warn: 'd' is an error pointer or valid

According to the documentation of the debugfs_create_dir() function, 
there is no need to check the return value of this function.
Just delete the dead code.
