LU-13263 osc: use LDLM_LOCK_RELEASE() if no lu_ref added

LU-13263 osc: use LDLM_LOCK_RELEASE() if no lu_ref added

In osc_ldlm_glimpse_ast(), LDLM_LOCK_PUT() is used after
LDLM_LOCK_GET() when no lu_ref has been added.
This causes a LBUG when USE_LU_REF is configured, so
change LDLM_LOCK_PUT() to LDLM_LOCK_RELEASE().
