[PATCH v2 1/5] reftable: remove unnecessary curly braces in reftable/tree.c

[Chandra Pratap <chandrapratap3519@xxxxxxxxx>]

According to Documentation/CodingGuidelines, single-line control-flow
statements must omit curly braces (except for some special cases).
Make reftable/tree.c adhere to this guideline.
