x86/platform/iosf_mbi: Check return value of debugfs_create properly
The code checks the result of the first debugfs_create call several
times and fails to check the result of the subsequent calls due to
missing assigments.
Add the missing assignments and check only for !res because
debugfs_create() returns only NULL on error and not an encoded error
code.
