ACPI: Remove redundant clearing of context->ret.pointer from acpi_run…

…_osc()

context->ret.pointer already gets set to NULL at the beginning of
acpi_run_osc() and it only gets assigned a new value in the success
path near the end of acpi_run_osc(), so the clearing of
context->ret.pointer (when status != AE_OK) at the end of
acpi_run_osc() is redundant since it will always already be NULL when
status != AE_OK.
