ACPI: EC: Avoid returning AE_OK on errors in address space handler

Browse Source 
[ Upstream commit c4bd7f1d78 ]

If an error code other than EINVAL, ENODEV or ETIME is returned
by acpi_ec_read() / acpi_ec_write(), then AE_OK is incorrectly
returned by acpi_ec_space_handler().

Fix this by only returning AE_OK on success, and return AE_ERROR
otherwise.
