[libvirt] [PATCH 4/5]: Move the sendtarget command into the login command

[Chris Lalancette <clalance redhat com>]

A small bugfix; we only need to call the iscsiadm sendtarget command when we are
first logging in; we don't need to do it for logout.  Move the sendtarget
command into the Login() function.

Changes since last time:
1)  Make const char *cmdsendtarget into const char *const cmdsendtarget based on
feedback from Jim.
