ec/acpi: Return error codes on timeout
The `send` and `recv` API functions currently print error messages
if a timeout occurs while polling the EC, but they perform the I/O
transaction regardless. This can put the EC in a bad state or
otherwise invoke undefined hardware behavior.
Most callers ignore the return value currently, but for callers
which do not, we should make sure our behavior is correct.
