The client SSC code should not depend on any of the CONFIG_NFSD config.
Replaced CONFIG_NFSD_V4 with CONFIG_NFS_V4_2_SSC_HELPER in nfs4file.c
and super.c. This patch also fixes the compiler warning of unused
variables when NFS_V4_2 is configured and NFSD_V4 is not.

OK. This looks better, and gives us a more direct dependency.
However looking independently at fs/Kconfig, I'm seeing
config NFS_V4_2_SSC_HELPER
tristate
default y if NFS_V4=y || NFS_FS=y
Shouldn't that rather be:
config NFS_V4_2_SSC_HELPER
bool
default y if NFS_V4_2 || NFSD_V4_2_INTER_SSC
...to allow us to get rid of these CONFIG_NFS_V4_2_SSC_HELPER #ifdefs
in fs/nfs? I suspect the above would also allow us to simplify the
dependencies in fs/nfsd/Kconfig for NFSD_V4_2_INTER_SSC too.
