Small memory leak fix (CVE-2019-6502 in #1586)
CVE-2019-6502 was assigned to what appears to be a very minor memory leak that only occurs on an error-case in a CLI tool. If util_connect_card fails, we still need to release the sc context previously allocated by sc_context_create else memory will leak.
