[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.
