NFSD: Hoist nfs42_ssc_open() into fs/nfs_common/nfs_ssc.c
Refactor: The infrastructure and details for calling the client's
ssc_open method can be hidden in nfs_ssc.c. This reduces the SSC
footprint in fs/nfsd/nfs4proc.c, a step toward removing that
file's dependency on <linux/nfs_fs.h>, which indirectly includes
<uapi/linux/nfs.h>.
The open and close functions are named "nfsd42_" since they are
meant to be invoked only by NFSD.
