Patch removes call to ast_free() in function send_ews_request_and_parse()
when request fails. The ast_free() function is always called after
send_ews_request_and_parse() (lines 547, 607 and 646) so it should not
produce any memory leaks.

P.S. I thought ast_free() is checking if it can free the momory, but
appereantly it doesn't.
