drm: apple: Fix broken MemDescRelay::release_descriptor callback number

Two callbacks for IOMFB::MemDescRelay seems to be dropped between 12.3
and 13.5 DCP firmware. This results in the renumbering of
MemDescRelay::release_descriptor from D456 to D454.
Noticed while when switching the display refresh rate to 50 Hz with a
14.5 system firmware on a M1 Max Macbook Pro.
