x86/boot/e820: Remove e820__range_remove()'s unused return parameter

None of the usage sites make use of the 'real_removed_size'
return parameter of e820__range_remove(), and it's hard
to contemplate much constructive use: E820 maps can have
holes, and removing a fixed range may result in removal
of any number of bytes from 0 to the requested size.

So remove this pointless calculation. This simplifies
the function a bit:

   text       data        bss        dec        hex    filename
   7645      44072          0      51717       ca05    e820.o.before
   7597      44072          0      51669       c9d5    e820.o.after
