Ian Rogers c5c8a26c0d perf hist: Fix memory leak of a perf_hpp_fmt ...

[ Upstream commit 0ca1f534a776cc7d42f2c33da4732b74ec2790cd ]

perf_hpp__column_unregister() removes an entry from a list but doesn't
free the memory causing a memory leak spotted by leak sanitizer.

Add the free while at the same time reducing the scope of the function
to static.
