[PATCH 07/12] iwlwifi: skip first element in the WTAS ACPI table

[Luca Coelho <luca@coelho.fi>]

From: Abhishek Naik <abhishek.naik@intel.com>

By mistake we were considering the first element of the WTAS wifi
package as part of the data we want to rid, but that element is the wifi
package signature (always 0x07), so it should be skipped.

Change the code to read the data starting from element 1 instead.
