NFS: dprintk() should not print negative fileids and inode numbers
A fileid in NFS is a uint64. There are some occurrences where dprintk()
outputs a signed fileid. This leads to confusion and more difficult to
read debugging (negative fileids matching positive inode numbers).

nfs: fix dead code of ipv6_addr_scope
The correct way to check on IPV6_ADDR_SCOPE_LINKLOCAL is to check with
the ipv6_addr_src_scope function.
Currently this can't be work, because ipv6_addr_scope returns a int with
a mask of IPV6_ADDR_SCOPE_MASK (0x00f0U) and IPV6_ADDR_SCOPE_LINKLOCAL
is 0x02. So the condition is always false.

When a task enters call_refreshresult with status 0 from call_refresh and
!rpcauth_uptodatecred(task) it enters call_refresh again with no rate-limiting
or max number of retries.
Instead of trying forever, make use of the retry path that other errors use.
This only seems to be possible when the crrefresh callback is gss_refresh_null,
which only happens when destroying the context.
To reproduce:
1) mount with sec=krb5 (or sec=sys with krb5 negotiated for non FSID specific
operations).
2) reboot - the client will be stuck and will need to be hard rebooted
