There is not a way to specify an attribute that applies to only one
target or target driver. This patch provides such an interface.

b103dd9949 qla2x00t: Fix q2t_close_session() 
The "force_close" sysfs attribute remains to exist for some time
after q2t_close_session() finished. Avoid that q2t_close_session()
invokes q2t_sess_put() more than once by removing a session from
the session list before returning. Avoid that that disabling a
target after q2t_close_session() has been invoked triggers a call
of q2t_sess_put(). Avoid that triggering the "force_close" sysfs
attribute after a target has been disabled triggers an additional
call of q2t_sess_put().
