scsi: qla2xxx: Fix logo flag for qlt_free_session_done()

commit a2390348c19d0819d525d375414a7cfdacb51a68 upstream.

Commit 3515832cc614 ("scsi: qla2xxx: Reset the logo flag, after target
re-login.")fixed the target re-login after session relogin is complete,
but missed out the qlt_free_session_done() path.

This patch clears send_els_logo flag in qlt_free_session_done()
callback.
