ARM: cleanup: debugfs error handling
Debugfs functions return NULL when they fail, or an error pointer
when not configured. The intention behind the error pointer is that
it appears as a valid pointer to the caller, and so the caller
continues inspite of debugfs not being available.
Debugfs failure should only ever be checked with (!ptr) and not the
IS_ERR*() functions.
