Show how much time kdump has waited for the network to be ready

Browse Source 
Relates: https://bugzilla.redhat.com/show_bug.cgi?id=2151504

Currently, when the network isn't ready, kdump would repeatedly print
the same info,

    [   29.537230] kdump[671]: Bad kdump network destination: 192.123.1.21
    [   30.559418] kdump[679]: Bad kdump network destination: 192.123.1.21
    [   31.580189] kdump[687]: Bad kdump network destination: 192.123.1.21

This is not user-friendly and users may think kdump has got stuck. So
also show much time has waited for the network to be ready,

    [   29.546258] kdump[673]: Waiting for network to be ready (50s / 10min)
    ...
    [   32.608967] kdump[697]: Waiting for network to be ready (56s / 10min)

Note kdump_get_ip_route no longer prints an error message and it's up to
the caller to determine the log level and print relevant messages. And
kdump_collect_netif_usage aborts when kdump_get_ip_route fails.
