    tmem: remove dumb check in do_tmem_destroy_pool
    
    do_tmem_destroy_pool is checking if pools == NULL. But, pools is a fixed
    array.
    
    Clang 3.5 will fail to compile xen/common/tmem.c with the following error:
    tmem.c:1848:18: error: comparison of array 'client->pools' equal to a null
    pointer is always false [-Werror,-Wtautological-pointer-compare]
        if ( client->pools == NULL )
    
    Coverity-ID:1055632
