[PATCH 28/50] x86/boot/e820: Rename update_e820() to e820__update_table()

[Ingo Molnar]

update_e820() should have 'e820' as a prefix as most of the other E820
functions have - but it's also a bit unclear about its purpose, as
it's unclear what is updated - the whole table, or an entry?

Also, the name does not express that it's a trivial wrapper
around sanitize_e820_table() that also prints out the resulting
table.

So rename it to e820__update_table_print(). This also makes it
harmonize with the e820__update_table_firmware() function which
has a very similar purpose.

No change in functionality.
