[kudu-CR] Fix use after free in RowSetTree

["Dan Burkert (Code Review)" <ge...@cloudera.org>]

Hello Adar Dembo, Todd Lipcon,

Change subject: Fix use after free in RowSetTree

Fix use after free in RowSetTree

This fixes a use after free bug which only causes issues on OS X. libstdcxx's
ref-counted strings on libstdc++ hide the bug by not destructing the stack
allocated string, because it had been copied elsewhere in the meantime.
