fuse: fix resolver to handle graph switches properly
perform resolution on the latest graph by caching it in state->itable
and use fuse_nodeid as just a hint to the possible final resolved inode
(in case it was resolved off the latest graph). GFID is the primary key
for resolving inodes on the latest graph.
