tool: Fixed incorrect return code if command line parser runs out of memory

In the rare instance where getparameter() may return PARAM_NO_MEM whilst
parsing a URL, cURL would return this error code, which is equivalent to
CURLE_FTP_ACCEPT_FAILED in cURL error codes terms.

Instead, return CURLE_FAILED_INIT and output the failure reason as per
the other usage of getparameter().
