[Libvir] [PATCH]: Make iSCSI login actually work

[Chris Lalancette <clalance redhat com>]

Hello,
     I mentioned this before, but this patch must have been dropped when Dan
committed storage stuff to CVS.  In order for iSCSI login to work properly, you
must properly --sendtargets before trying to login, otherwise your logins will
fail.  This patch just adds a --sendtargets command right before the login to
make sure things succeed.
