In the very unlikely event the cst3xx_i2c_write() fails inside of the
cst3xx_bootloader_enter() function 5 times in a row, the uninitalized
value of tmp will get compared to CST3XX_BOOTLDR_CHK_VAL. Initialize
the value of tmp to 0 so that in this unlikely event we are comparing
0 instead of an uninitalized variable.
