wifi: iwlwifi: Ensure prph_mac dump includes all addresses

Browse Source 
In prph_mac_iter, ensure that all required addresses are dumped
even if a read fails. Currently, if a read fails, the region dump
is stopped, preventing the creation of prph_mac.lst.

By dumping all addresses even if a read fails, we can accurately
determine which addresses were successfully read and which were not.
