[PATCH] nfsd4: fix struct file leak
We were failing to close on an error path, resulting in a leak of struct files
which could take a v4 server down fairly quickly.... So call
nfs4_close_delegation instead of just open-coding parts of it.
Simplify the cleanup on delegation failure while we're at it.
