[PATCH v7 4/7] t-reftable-pq: make merged_iter_pqueue_check() static

[Chandra Pratap <chandrapratap3519@gmail.com>]

merged_iter_pqueue_check() is a function previously defined in
reftable/pq_test.c (now t/unit-tests/t-reftable-pq.c) and used in
the testing of a priority queue as defined by reftable/pq.{c, h}.
As such, this function is only called by reftable/pq_test.c and it
makes little sense to expose it to non-testing code via reftable/pq.h.

Hence, make this function static and remove its prototype from
reftable/pq.h.
