Subject: asus-laptop: fix incorrect return value for write_acpi_int_ret if handle is NULL
From: Axel Lin <axel.lin@gmail.com>

According to the comments of write_acpi_int_ret(), write_acpi_int_ret()
should return 0 if write is successful, -1 else.  Thus if handle is NULL,
the write does not happen, it should return -1.
