Subject[PATCH RESEND] firmware: iSCSI: Remove unneeded #ifdef and associated dead code
Date
In commit 9d24622ced32 ("ACPI / IBFT: Fix incorrect <acpi/acpi.h>
inclusion in iSCSI boot firmware module"), the dependencies for
CONFIG_ISCSI_IBFT_FIND were changed to also include CONFIG_ACPI.

Inside drivers/firmware/iscsi_ibft.c, there is an "#ifdef CONFIG_ACPI"
block, while the whole file is only compiled with CONFIG_ISCSI_IBFT
enabled. As CONFIG_ISCSI_IBFT depends on CONFIG_ISCSI_IBFT_FIND
(which in turn depends on CONFIG_ACPI), CONFIG_ACPI will always be
enabled when we compile the file, hence the #ifdef is unnecessary and
the (empty) function inside the #else block can never be compiled and
they can both be removed.
