Bug Description

[Impact]
Multi-extent directories are not parsed correctly by grub's XFS code in 2.12~rc1, preventing it from loading files from directories with too many entries, such as the grub module directory.

This should only affect BIOS systems as they need to load the core grub modules from the module directory, whereas UEFI systems have them embedded in the ESP EFI image.

[Test plan]
TBD

[Where problems could occur]
TBD
