libext2fs: fix inode cache overruns

An inode cache slot will be overrun if a caller to ext2fs_read_inode_full()
or ext2fs_write_inode_full() attempts to read or write a full sized 156
byte inode when the target filesystem contains 128 byte inodes.  Limit the
copied inode to the smaller of the target filesystem's or the caller's
requested inode size.
