x86: cleanup e820_setup_gap(), add e820_search_gap(), v2
This is a preparatory patch for the next patch in series.
Moves some code from e820_setup_gap to a new function e820_search_gap.
This patch is a part of a bug fix where we walk the ACPI table to calculate
a gap for PCI optional devices.
v1->v2: Patch on top of tip/master.
Fixes a bug introduced in the last patch about the typeof "last".
Also the new function e820_search_gap now returns if we found a gap in
e820_map.
