Subject: [PATCH 3/3] staging: lustre: obdclass: fix checking for
 obd_init_checks()

The obd_init_checks() function can either return -EOVERFLOW or -EINVAL
but we accidentally ignore -EINVAL returns.

This patch is the right thing, but it's always a bit risky turning on
new checks and I haven't tested this.
