Subject: Bail out of kdump_check_net if no default interface is found
References: bsc#1058202
Upstream: merged
Git-commit: 0f07085aac4f506752e2cd41a43b34b85f3f09aa

If network is required but no default interface is found, dracut
spits spurious errors, such as:

/lib/kdump/setup-kdump.functions: line 471: /sys/class/net//addr_assign_type: No such file or directory
/lib/kdump/setup-kdump.functions: line 472: [: : integer expression expected
/lib/kdump/setup-kdump.functions: line 476: ethtool: command not found
