Fix "qla2xxx: terminate exchange when command is aborted by LIO"

This fixes commit f67924cc which was
commit 7359df25a53386dd33c223672bbd12cb49d0ce4f upstream.

When backporting the patch, there was an unused variable, and the printk
type was incorrect.  Fix this up by moving back to the correct type as
shown in commit 649ee05499d1257a3af0e10d961a1c52d9ef95b7 and remove the
unneeded variable.

This fixes up two build warnings.
