[PATCH 0/6] Apple NVMe fixes for macOS 15+ firmware / M4 support

Hi,

This series fixes a bunch of bugs that were working fine with M1/M2 NVMe
controllers with older firmware but are now starting to bite us.
With macOS 15 a new firmware is installed for the controller and both
XNU and the controller are a bit more strict now. This firmware is
required once we add M4 support.

The first patch fixes a panic that can happen when the controller fails
to initialize, which now happens for the first time with the new
firmware. The other fixes then make it work again.

Best,

Sven
