[illumos-Developer] WEBREV 706 beadm should accept 'umount' as well as 'unmount'

[Richard Lowe]

It looks like none of the be_cmds enum is used anymore, and that your
changes make it no longer synchronized with be_command_tbl.  I think
be_cmds should be removed.

The changes at lines 263 and 320 seem like they're fixing some other
bug(s), which should be filed and included in your commit message.
