maple_tree: avoid duplicate variable init in mast_spanning_rebalance()

Browse Source 
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.
