47a1dcfc75 scst_lib: Fix a recently introduced regression 
Due to patch "scst_lib: Fix a stack overflow" (r6500) there is a small
chance that not every scst_put_acg() call decreases the acg reference
count. Fix this.

4a858144ec qla2x00t: Convert __constant_htonl() into htonl() 
The function htonl() checks whether its argument is a constant
and is evaluated by the compiler if its argument is a constant.
This means that __constant_htonl() can be changed into htonl()
without any performance impact.

8fdd45a829 scst_lib: Fix a stack overflow 
Avoid that removing an acg with which a large number of sessions
has been associated triggers a stack overflow due to the following
recursive call chain:
    
scst_put_acg() -> scst_release_acg() -> scst_free_acg() -> scst_free_acn()
-> scst_check_reassign_sessions() -> scst_check_reassign_sess()
-> scst_put_acg().

6420070cb9 scst: Synchronize persistent reservation state between cluster nodes 
If cluster mode is enabled in SCST then the persistent reservation
state is shared and synchronized between multiple nodes via DLM LVB's
(lock value blocks).

The sysfs attribute cluster_mode controls whether or not persistent
reservation information is synchronized between cluster nodes.

Additionally, MODE SELECT commands are refused with cluster mode
enabled since mode pages are not yet synchronized between cluster
nodes.
