Yuezhang Mo af02c72d0b exfat: convert exfat_find_empty_entry() to use dentry cache ...

Before this conversion, each dentry traversed needs to be read
from the storage device or page cache. There are at least 16
dentries in a sector. This will result in frequent page cache
searches.

After this conversion, if all directory entries in a sector are
used, the sector only needs to be read once.
