HID: cp2112: Add parameter validation to data length
Syzkaller reported a stack OOB access in cp2112_write_req caused by lack
of parameter validation for the user input in I2C SMBUS ioctl in cp2112
driver
Add the parameter validation for the data->block[0] to be bounded by
I2C_SMBUS_BLOCK_MAX + the additional compatibility padding
