3.16.60-rc1 review patch. If anyone has any objections, please let me know.

commit e68088e78d82920632eba112b968e49d588d02a2 upstream.
Before commit e494f6a72839 ("[SCSI] improved eh timeout handler") it did not really matter whether or not abort handlers like srp_abort() called .scsi_done() when returning another value than SUCCESS. Since that commit however this matters. Hence only call .scsi_done() when returning SUCCESS.
