maple_tree: avoid duplicate variable init in mast_spanning_rebalance()
The local variables r_tmp and l_tmp in mast_spanning_rebalance() are
already initialized at its declaration; there is no need to assign the
value again.
Remove the duplicate initialization of {r,l}_tmp. No functional change.
Due to common compiler optimizations, also no change to object code.
This issue was identified with clang-analyzer's dead stores analysis.
