scst: fix memory leak in scst_proc_group_add()
Valgrind noticed that the "name" allocated in scst_proc_group_add() was
leaking. It turns out that scst_alloc_add_acg makes its own copy of the name
passed to it from this code, making the string duplication done here redundant
(and leaky). The change eliminates the string duplication (along with all its
associated error handling logic) and simply passes the (unowned) incoming
string down for duplication below.
