load_elf_library doesn't handle vm_brk failure although nothing really
indicates it cannot do that because the function is allowed to fail
due to vm_mmap failures already. This might be not a problem now
but later patch will make vm_brk killable (resp. mmap_sem for write
waiting will become killable) and so the failure will be more probable.
