isdn: isdnloop: fix pointer dereference bug
clang has spotted an ancient code bug and warns about it with: drivers/isdn/isdnloop/isdnloop.c:573:12: error: address of array 'card->rcard' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion] This is an array of pointers, so we should check if a specific pointer exists in the array before using it, not whether the array itself exists.
