libext2fs: ensure validate_entry doesn't read beyond blocksize

ext2fs_validate_entry would read beyond the end of the block to get
dirent->rec_len for certain arguments (like if blocksize ==
final_offset).  This patch adds a check so that doesn't happen, and
changes the types of the arguments to avoid a compiler warning.
