avf: fix race between avf process node and avf_delete_if(...)
It may happen that process node is suspended while it waits for response from adminq and during that time CLI or API process can call avf_delete_if. When avf process node resumes, it may happen that device is not there anymeore. This patch delegates interface deletion to process node, so CLI/API process just sends signal instead of deleting device instance itself. Type: fix Change-Id: I7f12e12df3071650f6e60ad7eb5af23b7acfe335 Signed-off-by: Damjan Marion <damarion@cisco.com>
