Removed inline specifier in functions that need to be exported

- `ngx_http_modsecurity_process_intervention` &
  `ngx_http_modsecurity_create_ctx` are exported by
  `ngx_http_modsecurity_module.c`, so they can't be declared as
  inline because the MSVC compiler will not export them in the
  generated object file.
