panasonic-laptop: fix acpi_pcc_write_sset return value 

In current implementation, acpi_pcc_write_sset return 1
if write is successful, 0 if write is failed.
But all the callers consider acpi_pcc_write_sset return 0
if write is successful and return negtive if write is failed.

This patch changes the implementation of acpi_pcc_write_sset to
return 0 if write is successful, -EIO if write is failed.
