Subject: [PATCH] BUILD: compression: remove a build warning

gcc emits this warning while building free_zlib() :
  src/compression.c: In function `free_zlib':
  src/compression.c:403: warning: 'pool' might be used uninitialized in this function

This is not a bug as the pool cannot take other values, but let's
pre-initialize is to null to fix the warning.
