x86/boot/e820: Harmonize the 'struct e820_table' fields

So the e820_table->map and e820_table->nr_map names are a bit
confusing, because it's not clear what a 'map' really means
(it could be a bitmap, or some other data structure), nor is
it clear what nr_map means (is it a current index, or some
other count).

Rename the fields from:

 e820_table->map        =>     e820_table->entries
 e820_table->nr_map     =>     e820_table->nr_entries

which makes it abundantly clear that these are entries
of the table, and that the size of the table is ->nr_entries.

Propagate the changes to all affected files. Where necessary,
adjust local variable names to better reflect the new field names.

No change in functionality.
