protocol/client: fixed registration of saved_fds
In client_open_cbk, client_opendir_cbk the list_add_tail macros were invoked with wrong
ordered arguments, causing the existing registered fd list to get unlinked from the
saved_fds list. The effects of this is far fetched - when transport disconnects, open
fds are no more marked bad as they are not reachable from the saved_fds list. After
reconnection, resumed access on this fd causes reference to invalid fds on the server.
It could appear in the form of 'unresolved fd' error, readdir happening on a file fd,
files reading from other files, etc.
