libafs: revert init req to use the real uid

The commit to use wrappers for creditial structure access
inadvertently changed the user id to be the effective uid instead of
the real uid, when no PAG is present, on linux.  Revert this so
setuid programs continue to work.

See commit eb8e55bba7740a87e07ef07bb4b789e6d4e36f0d
