Yuezhang Mo 92dcd7d6c6 exfat: support dynamic allocate bh for exfat_entry_set_cache
[ Upstream commit a3ff29a95f ]

In special cases, a file or a directory may occupied more than 19
directory entries, pre-allocating 3 bh is not enough. Such as
  - Support vendor secondary directory entry in the future.
  - Since file directory entry is damaged, the SecondaryCount
    field is bigger than 18.

So this commit supports dynamic allocation of bh.
