platform/chrome: cros_ec_proto: use cros_ec_map_error()
Use cros_ec_map_error() in cros_ec_get_host_event_wake_mask().
The behavior of cros_ec_get_host_event_wake_mask() slightly changed. It
is acceptable because the caller only needs it returns negative integers
for indicating errors. Especially, the EC_RES_INVALID_COMMAND still
maps to -EOPNOTSUPP.
