crush: remove invalid upmap items

crush: remove invalid upmap items

We can not cancel in verify_upmap if remap an osd to different root bucket,

cluster topology:
osd.0 ~ osd.29 belongs to datacenter 1
osd30 ~ osd.59 belongs to datacenter 2
crush rule:
  take datacenter 1
  chooseleaf 2 host
  emit
  take datacenter 2
  chooseleaf 2 host
  emit
The pg's primary osd in datacenter 1.

We should cancel the pgid from upmap_items like below
1) from [26,12,54,46] to [30,12,54,46]
pg_upmap_items [26,30]

2) from [16,25,53,31] to [40,25,53,0]
pg_upmap_items [16,20,31,0]
