[PATCH] IB/core: Fix missed clean call in registration path

[PATCH] IB/core: Fix missed clean call in registration path

[Leon Romanovsky]

In case of failure returned from query function in
IB device registration, we need to clean IB cache which
was missed.

This change fixes it.

Fixes: 3e153a93a1c1 ('IB/core: Save the device attributes on the device
structure')
