gfs2: Always check inode size of inline inodes
commit 70376c7ff31221f1d21db5611d8209e677781d3a upstream.
Check if the inode size of stuffed (inline) inodes is within the allowed
range when reading inodes from disk (gfs2_dinode_in()). This prevents
us from on-disk corruption.
The two checks in stuffed_readpage() and gfs2_unstuffer_page() that just
truncate inline data to the maximum allowed size don't actually make
sense, and they can be removed now as well.
