LU-20 kernel: remove rest of obsolete kernel patches

Remove several patches that have not been used in some time.
The bio_add_page patch addressed an performance issue with
SLES11 SP1 1.8 servers with direct IO. All platforms have
support for 64 bit quota so we can remove the patch to enable
it on old SLES11 platforms. We no longer need the function
security_inode_unlink exported since the fsfilt layer has now
been removed.
