[PATCH 1/1] NFSv4.2: Remove ifdef CONFIG_NFSD_V4 from nfsV4.2 client SSC code.

[Dai Ngo <dai.ngo@xxxxxxxxxx>]

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.
