wifi: iwlwifi: differentiate NIC error types
Instead of differentiating only sync/async, differentiate the type of error, and document that only reset handshake timeout (IWL_ERR_TYPE_RESET_HS_TIMEOUT) needs sync handling. The special sync handling is somewhat temporary, the idea is to later split the nic_error() method into error dump, synchronizing the dump, and SW reset methods, and the type is mostly in order to unify command queue full handling into that new architecture as well.
