The problem here is that the expandable space is being calculated incorrectly. Instead of using the EFI label info (DKIOCGETEFI), we should use DKIOCGMEDIAINFO[EXT].

Additionally, the expandable capacity should be reported as a multiple of the metaslab size, since that's how much can actually be used.

Additionally, we should not spam zfs_dbgmsg().
