  If both stripes are enabled, an improper AF grid configuration leads
the AF scene width to be wilder than the BDS width. Also, the second
stripe x_end is estimated based on the remaining AF scene width.
Therefore, the second stripe x_end will be greater than the second
stripe BDS width.

In this patch, if the second stripe x_end is greater than BDS width,
x_end will be set to BDS width.
