wifi: iwlwifi: avoid memory leak

Browse source

A caller of iwl_acpi_get_dsm_object must free the returned object.
iwl_acpi_get_dsm_integer returns immediately without freeing
it if the expected size is more than 8 bytes. Fix that.

Note that with the current code this will never happen, since the caller
of iwl_acpi_get_dsm_integer already checks that the expected size if
either 1 or 4 bytes, so it can't exceed 8 bytes.

While at it, print the DSM value instead of the return value, as this
was the intention in the first place.
