Description:
RFE: making slapi_ldap_init callable without snmp_collator_init.
The api slapi_ldap_init calls set_snmp_interaction_row, in which
interaction_table_mutex is held. This patch replaces NSPR PR_(Un)Lock with
slapi_(un)lock_mutex. The slapi_(un)lock_mutex skips locking if the mutex
is not initialized.
