hmp: drop bogus "[not inserted]"

Commit 3e9fab69 ("block: Add support for
throttling burst max in QMP and the command line.") introduced bogus
"[not inserted]" output, possibly due to a merge failure.  Remove this
artifact.

Output of 'info block'

scsi0-hd0: /images/f18-ppc64.qcow2 (qcow2)
 [not inserted]
scsi0-cd2: [not inserted]
    Removable device: not locked, tray closed

floppy0: [not inserted]
    Removable device: not locked, tray closed

sd0: [not inserted]
    Removable device: not locked, tray closed

There will be no additional lines between scsi0-hd0 and
scsi0-cd2.

At the same time, scsi0-hd0 already inserted, but still has
'[not inserted]' flag. This line should be removed.

This patch is to solve this.
