[PATCH v4 1/7] reftable: remove unncessary curly braces in reftable/pq.c

[Chandra Pratap <chandrapratap3519@gmail.com>]

According to Documentation/CodingGuidelines, control-flow statements
with a single line as their body must omit curly braces. Make
reftable/pq.c conform to this guideline. Besides that, remove
unnecessary newlines and variable assignment.
