[SCSI] iscsi: fixup set/get param functions
Reduce duplication in the software iscsi_transport modules by adding a libiscsi function to handle the common grunt work. This also has the drivers return specifc -EXXX values for different errors so userspace can finally handle them in a sane way. Also just pass the sysfs buffers to the drivers so HW iscsi can get/set its string values, like targetname, and initiatorname.
