luascript_func_check(): variable used uninitialized on FREECIV_NDEBUG build
Will push also to S2_6.
As fc_assert_ret_val() is one of the macros of the fc_assert family that we still have active even on --disable-debug builds, there's no *currently* functional bug, and this patch causes compilation failure instead.
Even in case of fc_assert_ret_val(), it's forbidden to have functionality inside it, for the purposes of being able to disable them on ndebug builds on some future versions. So this patch is still needed, just have to fix the compile error.

No, that was true for S2_6 only. In later branches the functionality is broken + there's no compile failure with the patch -> going to push existing patch to S3_0+, and will do nothing to S2_6.
luascript_func_check() sets variable pfunc within fc_assert_ret_val(), i.e., it's not set in FREECIV_NDEBUG builds. Later code expects it to be set.
