Linux 4.8 no longer boots, as it runs out of descriptor space. Readding the mapping allows reuse, and the next AllocatePool will likely not add a new mapping.
Also fix some small issues found while debugging.
v2, updated: efi_loader: Fix memory map size check to avoid out-of-bounds access - (Hopefully) clarified commit message efi_loader: Track size of pool allocations to allow freeing - rebased on top of 'efi_loader: Fix crash on 32-bit systems' - assert correct address in efi_free_pool - use EFI_PAGE_MASK instead of 0xfff, EFI_PAGE_SHIFT likewise
