nvmet-fc: check successful reference in nvmet_fc_find_target_assoc
When searching for an association based on an association id, when there
is a match, the code takes a reference. However, it is not validating
that the reference taking was successful.
Check the status of the reference. If unsuccessful, the device is being
deleted and should be ignored.
