after the client and session have been recovered, loop through the client's list of open state, calling nfs41_open_reclaim() and updating the stateid on success
nfs41_open_state saves the share_access and share_deny fields from the initial open, for use with nfs41_open_reclaim()

open state is added to the client's list on a successful call to nfs41_open(), and removed from the list on nfs41_close() regardless of success

very similar to the issue with nfs41_open_state, an abandoned upcall could outlive its mount. to prevent their nfs41_root from being freed, upcalls need to hold a reference until they're finished. this also keeps all of its clients/sessions/rpc connections alive

fixes a memory leak that occurs when a readdir loop doesn't complete, since the cookie was only freed on the last readdir upcall. by storing the cookie with nfs41_open_state, we can avoid passing the cookie to the driver and back, and not worry about having to free it separately

in handle_mount(), the call to nfs41_lookup() requires a mutable nfs41_abs_path because it can change on referrals, so make a copy for it
removed unused fields in struct nfs41_root and related arguments to nfs41_root_create()

because we no longer have to convert strings from unicode, we can avoid copying them out of the upcall buffer
