ext4: support large block size in ext4_calculate_overhead()
ext4_calculate_overhead() used a single page for its bitmap buffer, which
worked fine when PAGE_SIZE >= block size. However, with block size greater
than page size (BS > PS) support, the bitmap can exceed a single page.
To address this, we now use kvmalloc() to allocate memory of the filesystem
block size, to properly support BS > PS.
