The nfsservctl systemcall isn't used but recent nfs-utils releases for
exporting filesystems, and consequently the code that is uses -
exp_export - has suffered some bitrot.

Particular:
  - some newly added fields in 'struct svc_export' are being initialised
    properly.
  - the return value is now always -ENOMEM ...

This patch fixes both these problems.
