[PATCH] ACPICA: Delete an unnecessary check before the function call "acpi_ds_delete_walk_state"

The acpi_ds_delete_walk_state() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
