fix(io_stm32image): uninitialized variable warning
Fixes implementation against build warning reported by GCC: drivers/st/io/io_stm32image.c: In function ‘stm32image_partition_read’: drivers/st/io/io_stm32image.c:249:6: error: ‘result’ may be used uninitialized in this function [-Werror=maybe-uninitialized] int result; ^~~~~~ Actually, by construction the current implementation of function stm32image_partition_read() does not mandate result to be initialized since it always reaches the exit point with a valid value in 'result'. Yet, this change prevents compiler from complaining and is more robust against future changes in the implementation.
