values to attributes that support multiple values, e.g. 'allowed_portal'.
Hence revert r7014.

283b30f603 scst: add thread_index sysfs attribute 
This attribute exports per LUN thread index assigned by
scst_add_threads(). It can be used to look up which export thread is
serving which target since this index also appears in the export thread
name. This information then could be used to set CPU affinity for those threads to improve performance.
