efi_loader: fix efi_debug_image_info_normal allocation

Browse Source 
When adding a new EFI Debug Image Info entry, we allocate memory for a new
EFI Debug Image Info Normal structure and we add a new entry into the EFI
Debug Image Info Table, which is in fact just a pointer to the allocated
structure.

However, when allocating memory for the new structure we allocate memory
for the wrong type, leading to allocating memory for just a pointer instead
of the desired structure.

Fix the type used during allocation.
