Subject: maple_tree: fix node allocation testing on 32 bit
From: Liam R. Howlett <Liam.Howlett@xxxxxxxxxx>
commit ef5c3de5211b5a3a8102b25aa83eb4cde65ac2fd upstream.
Internal node counting was altered and the 64 bit test was updated,
however the 32bit test was missed.
Restore the 32bit test to a functional state.
