Subject: [PATCH] maple_tree: fix node allocation testing on 32 bit
References: bsc#1012628
Patch-mainline: 6.4.7
Git-commit: ef5c3de5211b5a3a8102b25aa83eb4cde65ac2fd
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.
