I want to confirm it's nothing to worry about. I have the same card.
I don't know if you can hide that message but you can remove these bits [ 82.356109] b43-phy0: Hardware crypto acceleration not supported by firmware [ 82.356112] b43-phy0: QoS not supported by firmwareby not asking the b43 kernel module to not use those features. It can be done by making a file /etc/modprobe.d/b43.conf with the following content:
options b43 nohwcrypt=1 qos=0
