ext4: fix a double free in ext4_register_li_request
In ext4_register_li_request, we malloc a ext4_li_request and
inserts it into ext4_li_info->li_request_list. In case of any
error later, we free it in the end. But if we have some error
in ext4_run_lazyinit_thread, the whole li_request_list will be
dropped and freed in it. So we will double free this ext4_li_request.
This patch just sets elr to NULL after it is inserted to the list
so that the latter kfree won't double free it.
