fix(allwinner): fix variable may be used uninitialized error
When building with LTO, the compiler observes that i2c_read() can return
without writing val, declaring the variable may be used unnitialized.
However, there is a sufficient error check that will prevent an actual
use. So calm the compiler by giving a safe default.
