Subject: [PATCH] [LIO-Target/ConfigFS]: Convert TPG and Node attributes to use updated ConfigFS macros

Use updated include/linux/configfs.h macros from commit 71fc659e337dcc5941f6f64f6c8abfb6b477fd7c

This commit removed the need for our internal 'to_<name>()' functions, and renames
the TPG and Node attribute code to not be dependent on structure name.
