slapadd hangs if bi_tool_entry_put() fails.

Tested with back-ldif patched for bi_tool_entry_put() to return NOID
after 6 entries, and on master with mdb and an LDIF > DB maxsize.

Test program enclosed.  Backtrace:

I don't want to touch that code, don't remember why nearby code uses
ldap_pvt_tread_yield() instead of the clean way of having two conds
(one for producer and one for consumer to wait for).
