nfs_common: Remove unused nfs_ssc_client_ops infrastructure
Clean up: Commit 75333d48f922 ("NFSD: fix use-after-free in
__nfs42_ssc_open()") addressed a use-after-free bug by removing the
nfsd4_interssc_disconnect() function. Post-copy clean-up was then
delegated to NFSD's laundromat.
Since that commit, the nfs_do_sb_deactive() wrapper function and the
entire nfs_ssc_client_ops infrastructure no longer have any
consumers. This includes nfs_do_sb_deactive(), struct
nfs_ssc_client_ops, nfs_ssc_register(), nfs_ssc_unregister(), and
related registrations in the NFS client.
