(ITS#3602) potential SIGSEGV in bdb_referrals()

There's potential for a SIGSEGV (it ocurred on one of our machines) when
bdb_dn2entry() returns an error other than 0 or DB_NOTFOUND, thus not setting
"ei", because "ei" is later dereferenced __before__ checking the return code.
I'm unable at the moment to reproduce the cause of the problem, which seems to
be very unlikely to occur except in very particular circumstances. A fix is
being committed to HEAD.
