SCSI fixes on 20160304

Browse source 
Two fairly simple fixes.  One is a regression with ipr firmware
 loading caused by one of the trivial patches in the last merge window
 which failed to strip the \n from the file name string, so now the
 firmware loader no longer works leading to a lot of unhappy ipr users;
 fix by stripping the \n.  The second is a memory leak within SCSI: the
 BLK_PREP_INVALID state was introduced a recent fix but we forgot to
 account for it correctly when freeing state, resulting in memory
 leakage.  Add the correct state freeing in scsi_prep_return().
