ACPI: EC: Abort address space access upon error

[ Upstream commit f6f172dc6a6d7775b2df6adfd1350700e9a847ec ]

When a multi-byte address space access is requested, acpi_ec_read()/
acpi_ec_write() is being called multiple times.

Abort such operations if a single call to acpi_ec_read() /
acpi_ec_write() fails, as the data read from / written to the EC
might be incomplete.
