Subject: [PATCH] ACPI / EC: Free saved_ec on error exit path

Smatch detected two memory leaks on saved_ec:

drivers/acpi/ec.c:1070 acpi_ec_ecdt_probe() warn: possible
  memory leak of 'saved_ec'
drivers/acpi/ec.c:1109 acpi_ec_ecdt_probe() warn: possible
  memory leak of 'saved_ec'

Free saved_ec on these two error exit paths to stop the memory
leak.  Note that saved_ec maybe null, but kfree on null is allowed.
