exfat: optimize allocation bitmap loading time
Loading the allocation bitmap is very slow if user set the small cluster
size on large partition.
For optimizing it, This patch uses sb_breadahead() read the allocation
bitmap. It will improve the mount time.
The following is the result of about 4TB partition(2KB cluster size)
on my target.
