perf map: Remove kernel map before updating start and end addresses

In a debug build there is validation that mmap lists are sorted when
taking a lock. In machine__update_kernel_mmap() the start and end
addresses are updated resulting in an unsorted list before the map is
removed from the list. When the map is removed, the lock is taken which
triggers the validation and the failure:

  $ perf test "object code reading"
  --- start ---
  perf: util/maps.c:88: check_invariants: Assertion `map__start(prev) <= map__start(map)' failed.
  Aborted

Fix it by updating the addresses after removal, but before insertion.
The bug depends on the ordering and type of debug info on the system and
doesn't reproduce everywhere.

Fixes: 659ad3492b913c90 ("perf maps: Switch from rbtree to lazily sorted array for addresses")
