hwmon: (asus_rog_ryujin) Synchronize HID command and report handling

Browse source

rog_ryujin_execute_cmd() holds status_report_request_lock while
reinitializing a completion, intending to exclude raw-event handling.
However, rog_ryujin_raw_event() does not acquire the lock when it updates
the completion. A response can therefore race with reinit_completion() and
be lost, leaving the command to time out.

Hold the lock while parsing reports and updating their completions. Use the
irqsave variants in both paths because raw-event handling may run in
interrupt context.
