iwlwifi: skip first element in the WTAS ACPI table

[ Upstream commit 19426d54302e199b3fd2d575f926a13af66be2b9 ]

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.
