x86/efistub: Fix PCI ROM preservation in mixed mode
[ Upstream commit8b94da9255
] preserve_pci_rom_image() was accessing the romsize field in efi_pci_io_protocol_t directly instead of using the efi_table_attr() helper. This prevents the ROM image from being saved correctly during a mixed mode boot. Fixes:2c3625cb9f
