unmarshal error when fetching report

[karenetheridge]

kosh-prod --json device E346530X8B02780 report gives error: "json: cannot unmarshal number 14400.0 into Go struct field Disk.latest_report.disks.size of type int"

interestingly, however, the report doesn't actually contain a value 14400.0 -- I only see an integer 14400.
