[PATCH 2/4] efi: Fix requests to allocate GRUB_MEMORY_AVAILABLE

[Josh Triplett]

EFI firmware refuses to allocate memory of type
GRUB_EFI_CONVENTIONAL_MEMORY, because that indicates a block of
available memory that other allocations (or the OS) would then step on.
Map GRUB_MEMORY_AVAILABLE to GRUB_EFI_LOADER_CODE instead.

        * grub-core/mmap/efi/mmap.c (make_efi_memtype): Map
          GRUB_MEMORY_AVAILABLE to GRUB_EFI_LOADER_CODE rather than
          GRUB_EFI_CONVENTIONAL_MEMORY.  EFI firmware refuses to allocate
          memory of type GRUB_EFI_CONVENTIONAL_MEMORY, because that
          indicates a block of available memory that other allocations (or
          the OS) would then step on.
