Prior to this commit, i2c and at24 may be used uninitialized on line
113, 117, 129, and 143 when gd32_at24_wr_test() is called the second
time because these two variables are not static. I don't think making
them static is the correct fix because i2c is released at the end of
this function. Fixed by removing the `if (!initialized)` condition
surrounding the initialization of i2c and at24, making them initialized
at every call to this function.
