SUNRPC: remove RPC pipefs mount point manipulations from RPC clients code
v2:
1) Updated due to changes in the first patch of the series.
Now, with RPC pipefs mount notifications handling in RPC clients, we can remove
mount point creation and destruction. RPC clients dentries will be created on
PipeFS mount event and removed on umount event.
