nfs_common: fix Kconfig for NFS_COMMON_LOCALIO_SUPPORT

nfs_common: fix Kconfig for NFS_COMMON_LOCALIO_SUPPORT

The 'default n' that was in NFS_COMMON_LOCALIO_SUPPORT caused these
extra defaults to be missed:
        default y if NFSD=y || NFS_FS=y
	default m if NFSD=m && NFS_FS=m

Remove the 'default n' for NFS_COMMON_LOCALIO_SUPPORT so that the
correct tristate is selected based on how NFSD and NFS_FS are
configured.  This fixes the reported case where NFS_FS=y but
NFS_COMMON_LOCALIO_SUPPORT=m, it is now correctly set to =y.

In addition, add extra 'depends on NFS_LOCALIO' to
NFS_COMMON_LOCALIO_SUPPORT so that if NFS_LOCALIO isn't set then
NFS_COMMON_LOCALIO_SUPPORT will not be either.
