Ovidiu Panait 3f351cd358 cpu: microblaze: add error handling in microblaze_cpu_get_desc() ...

Check snprintf() return value for errors.

Make microblaze_cpu_get_desc() directly return snprintf() error code if
ret < 0. Otherwise, if the return value is greater than or equal to size,
the resulting string is truncated, so return -ENOSPC.
