NFSD: Fix error return code in nfsd4_interssc_connect()

Browse Source 
[ Upstream commit 54185267e1fe476875e649bb18e1c4254c123305 ]

'status' has been overwritten to 0 after nfsd4_ssc_setup_dul(), this
cause 0 will be return in vfs_kern_mount() error case. Fix to return
nfserr_nodev in this error.

Fixes: f4e44b393389 ("NFSD: delay unmount source's export after inter-server copy completed.")
