Modified Files: src/sys/dev/usb: uhid.c Log Message: uhid(4): Omit needless softint indirection. USB xfer callbacks already run in softint context at IPL_SOFTSERIAL, and I see no reason why the call to psignal must happen instead at the lower priority of IPL_SOFTCLOCK, so let's avoid using up the scarce resource of softints for something that doesn't need 'em. While here, use atomic_store_relaxed to update sc->sc_async and atomic_load_relaxed to optimisitcally test it without acquiring proc_lock.
