[PATCH v2 2/2] fix crash if agent interface is removed

[Frediano Ziglio <fziglio@xxxxxxxxxx>]

Removing an interface cause SpiceBaseInstance->st to be set to NULL.
This pointer was then deferenced in agent code.
As SpiceBaseInstance should not be used after this call make sure
we don't keep pointers to it.
