i2c_helper_linux.c: Use a fixed-size buffer
Given that the buffer size is known in advance, using malloc() is not
necessary. To avoid open-coding buffer sizes, add some trailing null
characters to `I2C_DEV_PREFIX`, as placeholders for bus number digits.
Finally, replace the now-unnecessary `goto` statements with `return`.
