The cede latency stuff is relatively new and we don't need to complain about
it not working on older firmware.

Seems like a reasonable change. CC'ing Vaidy and Gautham to look even
more closely at the patch.

Removing the printk is reasonable. The failure case is noise in older
firmware while the success case may not be very informative.
