Prompted by #46, I have taken the time looking at `pspnet_adhocctl.prx`
in older firmware versions via Ghidra (thanks @sajattack) and some
early Adhoc-capable titles like Ridge Racer and Hot Shot's Golf, I
have concluded that the order of elements in the `SceNetAdhocctlParams`
struct to have always been `nickname`, followed by `bssid`. Not changed
in any later firmware revision. This commit resolves this discrepancy.
