ARC: module: Fix !CONFIG_ARC_DW2_UNWIND builds
commit d65283f7b695b5 added mod->arch.secstr under CONFIG_ARC_DW2_UNWIND, but used it unconditionally which broke builds when the option was disabled. Fix that by adjusting the #ifdef guard. And while at it add a missing guard (for unwinder) in module.c as well Reported-by: Waldemar Brodkorb <wbx@openadk.org> Cc: stable@vger.kernel.org #4.9 Fixes: d65283f7b695b5 ("ARC: module: elide loop to save reference to .eh_frame") Tested-by: Anton Kolesov <akolesov@synopsys.com> Reviewed-by: Alexey Brodkin <abrodkin@synopsys.com> [abrodkin: provided fixlet to Kconfig per failure in allnoconfig build] Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
