LU-1497 client: SLES11 SP0 client build is broken.

LU-1497 client: SLES11 SP0 client build is broken.

With the addition of client improvements new linux kernel
apis are exposed to the llite layer. Those apis can be
missing or have a different format in earlier kernels.
This is the case for SLES11 SP0 clients for the case
of the vma handling and the function inode_newsize_ok
that is missing. This patch fixes those issues. Final
bug is a fix to a configure test for a function from
the linux crypto api.
