drivers/char/ipmi: memcpy, need additional 2 bytes to avoid memory overflow
commit a5f2b3d6a738e7d4180012fe7b541172f8c8dcea upstream.
When calling memcpy, read_data and write_data need additional 2 bytes.
write_data:
for checking: "if (size > IPMI_MAX_MSG_LENGTH)"
for operating: "memcpy(bt->write_data + 3, data + 1, size - 1)"
read_data:
for checking: "if (msg_len < 3 || msg_len > IPMI_MAX_MSG_LENGTH)"
for operating: "memcpy(data + 2, bt->read_data + 4, msg_len - 2)"
