[PATCH v2 02/13] dracut-early-kdump: fix shellcheck findings

[Philipp Rudo]

Fix the following issues found by shellcheck. For the second one disable
shellcheck as EARLY_KEXEC_ARGS can contain multiple arguments.

In dracut-early-kdump.sh line 9:
EARLY_KDUMP_KERNELVER=""
^-------------------^ SC2034: EARLY_KDUMP_KERNELVER appears unused. Verify use (or export
if used externally).

In dracut-early-kdump.sh line 61:
    if $KEXEC $EARLY_KEXEC_ARGS $standard_kexec_args \
              ^---------------^ SC2086: Double quote to prevent globbing and word
splitting.
