nfs: changes for using nameless lookup and anonymous FDs

- Use gfid to create filehandle instead of encoding path components
- Utilize nameless lookups of GFID for deep resolution instead of
  crawling the namespace with component hints
- Use anonymous FDs for file based operations
- Do away with fdcaching code for files and dirs
