nfs: fix dead code of ipv6_addr_scope
commit a8c2275493b866961f4429a741251c630c4fc6d7 upstream.
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.
