iwlwifi: mvm: add description to a few generic assert numbers
FW asserts 0x70, 0x71, and 0x73 all just mean that the real error happened in another MAC, and to look there for the problem. Add their descriptions to the assert number lookup table so users get a nicer error message in the logs. Also, since the 4 most-significant bits of the assert number are dynamic, and depend on which MAC the assert occurred on, ignore those bits when looking up the assert name.
