Ondrej Mosnacek b37fdd9410 selinux: policydb - fix byte order and alignment issues
commit 5df275cd4c upstream.

Do the LE conversions before doing the Infiniband-related range checks.
The incorrect checks are otherwise causing a failure to load any policy
with an ibendportcon rule on BE systems. This can be reproduced by
running (on e.g. ppc64):

cat >my_module.cil <<EOF
(type test_ibendport_t)
(roletype object_r test_ibendport_t)
(ibendportcon mlx4_0 1 (system_u object_r test_ibendport_t ((s0) (s0))))
EOF
semodule -i my_module.cil

Also, fix loading/storing the 64-bit subnet prefix for OCON_IBPKEY to
use a correctly aligned buffer.

Finally, do not use the 'nodebuf' (u32) buffer where 'buf' (__le32)
should be used instead.

Tested internally on a ppc64 machine with a RHEL 7 kernel with this
patch applied.
