This would be valid if the path was something like \remote-machine\HKLM.

But if the first if block was true and the second block was false, the registry path is invalid. Windows does not accept registry paths such as \HKLM.

In summary:

True + True = valid path, but not supported in Wine.
True + False = invalid path
False + True = impossible
False + False = valid path

The original check was better:
if (key_name[0] == '\' && key_name[1] == '\')
{
    reg_message(STRING_NO_REMOTE);
    return 1;
}
It was also unclear why you perform the path[0] == '\' check in path_get_key() and path_get_rootkey_name(). One common check should be enough. The original version of this patch did this (now superseded). But I see you made some changes around the reg_delete() function.
