Make it possible to forcibly close SRP and FC sessions via sysfs

Browse Source 
That patch contains the following changes:
* Move the code for creating a "close_sess" sysfs attribute from iscsi-scst to
  the SCST core such that it becomes available for other target drivers. This
  does not change the functionality of iscsi-scst.
* Add code in ib_srpt and qla2x00t to allow a session to be forcibly closed from
  user space.
