nfsd: fix error handling in nfs4_set_delegation()
I noticed a memory corruption crash in nfsd in
4.17-rc1. This patch corrects the issue.
Fix to return error if the delegation couldn't be hashed or there was
a recall in progress. Use the existing error path instead of
destroy_delegation() for readability.
