[ Upstream commit a3ff29a95fde16906304455aa8c0bd84eb770258 ]
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.
