[PATCH] Make keyctl(KEYCTL_JOIN_SESSION_KEYRING) use the correct arg

[David Howells <dhowells@redhat.com>]

The attached patch makes keyctl() use the correct argument when invoking the
KEYCTL_JOIN_SESSION_KEYRING function.

I'm not sure how this evaded testing before, but I suspect the compiler was
kind and made both argument registers hold the same value.

Thanks to Kevin Coffman <kwc@citi.umich.edu> for spotting this.
