Subject: [PATCH] mwifiex: report error to MMC core if we cannot suspend

commit dd321acddc3be1371263b8c9e6c6f2af89f63d57 upstream.

When host_sleep_config command fails we should return error to
MMC core to indicate the failure for our device.

The misspelled variable is also removed as it's redundant.
