[DLM] Fix memory leak in dlm_add_member() when dlm_node_weight() returns less than zero 

There's a memory leak in fs/dlm/member.c::dlm_add_member().

If "dlm_node_weight(ls->ls_name, nodeid)" returns < 0, then
we'll return without freeing the memory allocated to the (at
that point yet unused) 'memb'.
This patch frees the allocated memory in that case and thus
avoids the leak.
