Dan Carpenter 690b2549b1 i2c: ismt: prevent memory corruption in ismt_access()
The "data->block[0]" variable comes from the user and is a number
between 0-255.  It needs to be capped to prevent writing beyond the end
of dma_buffer[].

Fixes: 5e9a97b1f4 ("i2c: ismt: Adding support for I2C_SMBUS_BLOCK_PROC_CALL")
