squash! mem_pool: add GIT_TRACE_MEMPOOL support

b358145 (mem_pool: add GIT_TRACE_MEMPOOL support, 2018-10-04)
adds a format that uses %p format identifiers which are meant to be
used by (void *) which will be reported under pedantic, as it was
not explicitly cast.

add cast and while at it, reformat the affected lines so they fit
better under the 80 column limit.
