debugfs: Fix module state check condition

The '#ifdef MODULE' check in the original commit does not work as intended.
The code under the check is not built at all if CONFIG_DEBUG_FS=y. Fix this
by using a correct check.

Fixes: 275678e ("debugfs: Check module state before warning in {full/open}_proxy_open()")
