[nft PATCH 1/7] nft_ctx_free: Fix for wrong argument passed to cache_release

[Phil Sutter <phil@nwl.cc>]

nft_ctx_free() should not refer to the global 'nft' variable, this will
break as soon as the function is moved away from main.c. In order to use
the cache reference from passed argument, the latter must not be const.
