[PATCH 39/53] ecryptfs: stop using d_add().

[NeilBrown]

From: NeilBrown <neil at brown.name>

"Best practice" is to use d_splice_alias() at the end of a ->lookup
function.  d_add() often works and is not incorrect in ecryptfs, but as
it is planned to remove d_add(), change to use d_splice_alias().
