  lib-auth: Prevent double-disconnect

When disconnecting, it's possible that
disconnect gets called twice by some callback,
so protect it with a boolean.

Fixes Panic: file hash.c: line 152 (hash_table_clear): assertion failed: (table->frozen == 0)

  Changed paths:
    M src/auth/db-lua.c

  Log Message:
  -----------
  auth: db-lua - Do not assert-crash if given parameter was not auth_request

Use luaL_error instead that will back out more gracefully.

Fixes Panic: file db-lua.c: line 279 (auth_lua_check_auth_request): assertion failed: (lua_istable(script->L, arg))
