kdump/kdump-kdump_echo-and-kdump_logger-helpers.patch

From: Lance Wang <lzwang@suse.com>

Subject: load.sh: introduce kdump_echo and kdump_logger helpers
References: bsc#951144
Upstream: merged
Git-commit: b76b8fccbac6a7d2340d0452a6ba86530f588bfa

Instead of checking the verbosity flags every time, check them once
and provide an appropriate function definition.
