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.
