winpgnt: fix GUI removal of encrypted keys.

Browse Source 
The GUI loop that responded to the 'Remove Key' button in the key list
worked by actually trying to retrieve a pointer to the ssh_key for a
stored key, and then passing that back to the delete function. But
when a key is encrypted, that pointer is NULL, so we segfaulted.

Fixed by changing pageant_delete_ssh2_key() to take a numeric index in
the list instead of a key pointer.
