Fix controllers address check in cases of controller-based privacy.
When controller has been instructed by the host to use privacy
the controller should look up the peer identity address and generate
an address based on the local IRK. In the case where no match
is found or the local IRK is all zeroes the controller shall use
the fallback address. If the fallback address is not valid the
controller shall return invalid params.
This commit fixes these issues:
- Starting a private advertiser without valid random address set
but a valid local IRK exists. In this case the advertiser should
be able to advertise using the RPA regardless of a valid random
or public address.
- Starting a private advertiser with a fallback to the public
address type or an adveriser using public address does not
check if a valid public address exists. The host cannot
advertise with an all-zero public address.
