916dee314f Another bug fix for aborting SCST commands: commands in state 
SRPT_STATE_NEW are now aborted properly too. Until now aborting an
SCST command that had state SRPT_STATE_NEW triggered a sBUG_ON()
statement in scst_tgt_cmd_done().

af3245ca0a - Only retry creating a temp group name the max possible names 
to prevent an infinite loop. Since we're using rand() here,
  it's possible we could exit the loop with no unique name.     
  However, this is pretty unlikely considering thousands
  if temp group names would have to already exist.
- Fail out if we can't come up with a temp group name and just
  use the original specified.

1afa718390 Ported the OFED 1.5 commit http://www.openfabrics.org/git/?p=ofed_1_5/linux-2.6.git;a=commitdiff;h=ce223537aeb05c9e4c36eab2b509fb98a33ba359: 
replaced dma_*map* calls by ib_dma_*map* calls. Added the conversion
of dma_sync_single_for_device() to ib_dma_sync_single_for_device().
This only changes the behavior of SRPT for those IB interfaces whose
driver implements the ib_dma_mapping_ops operations.

The OFED commit made a.o. ib_srpt.c compile on 2.6.30 and later kernels.
Although the SCST ib_srpt.c code already compiles on a 2.6.30 kernel, this
commit has been ported to SCST because the source code of the OFED
implementation is cleaner. This commit does not change any functionality
of SCST's SRPT.
