x86/boot/e820: Rename 'e820_map' variables to 'e820_array'
In line with the rename to 'struct e820_array', harmonize the naming of common e820 table variable names as well: e820 => e820_array e820_saved => e820_array_saved e820_map => e820_array initial_e820 => e820_array_init This makes the variable names more consistent and easier to grep for. No change in functionality.
