FAT: buffer overflow with FAT12/16
Last commit 3831530dcb7b71329c272ccd6181f8038b6a6dd0a was intended "explicitly specify FAT12/16 root directory parsing buffer size, instead of relying on cluster size". Howver, the underlying function requires the size of the buffer in blocks, not in bytes, and instead of passing a double sector size a request for 1024 blocks is sent. This generates a buffer overflow with overwriting of other structure (in the case seen, USB structures were overwritten).
