Subject: [PATCH 157/303] btrfs-progs: move global reserve to overall summary

It looks confusing among the chunks, it is not in fact a chunk type.

Sample:
Overall:
    Device size:                  35.00GiB
    Device allocated:              8.07GiB
    Device unallocated:           26.93GiB
    Used:                          1.12MiB
    Free (Estimated):             17.57GiB      (Max: 30.98GiB, min: 17.52GiB)
    Data to device ratio:             50 %
    Global reserve:               16.00MiB      (used: 0.00B)
