Revert "ACPI: PM: s2idle: Cancel wakeup before dispatching EC GPE"

This reverts commit e799974e7cbb2e77ec12431512e155574c6ed333 which is
commit dc0075ba7f387fe4c48a8c674b11ab6f374a6acc upstream.

It's been reported to cause problems with a number of Fedora and Arch
Linux users, so drop it for now until that is resolved.
