NFS: sysfs: fix leak when nfs_client kobject add fails

Browse Source 
[ Upstream commit 7a7a3456520b309a0bffa1d9d62bd6c9dcab89b3 ]

If adding the second kobject fails, drop both references to avoid sysfs
residue and memory leak.

Fixes: e96f9268ee ("NFS: Make all of /sys/fs/nfs network-namespace unique")
