x86/boot/e820: Use 'enum e820_type' when handling the e820 region type
The E820 region type is put into four different types (!) when used in function
parameters or local variables:
unsigned type;
int type;
unsigned long current_type;
u32 type;
Use 'enum e820_type' in all these cases instead.
No change in functionality.
