        Don't run kdump_check_setup_iscsi in a subshell in order to collect needed
        network interfaces
    
        Currently, dumping to iSCSI target fails because the global array
        (unique_netifs) that stores the network interfaces needed by kdump is
        empty. The root cause is change of the array made in a subshell (a child
        process) is inaccessible to the parent process. So don't run
        kdump_check_setup_iscsi in a subshell.
