IB/mad: Convert allocations from kmem_cache to kzalloc
This patch implements allocating alternate receive MAD buffers within the MAD
stack. Support for OPA to send/recv variable sized MADs is implemented later.
1) Convert MAD allocations from kmem_cache to kzalloc
kzalloc is more flexible to support devices with different sized MADs
and research and testing showed that the current use of kmem_cache does
not provide performance benefits over kzalloc.
2) Change struct ib_mad_private to use a flex array for the mad data
3) Allocate ib_mad_private based on the size specified by devices in
rdma_max_mad_size.
4) Carry the allocated size in ib_mad_private to be used when processing
ib_mad_private objects.
5) Alter DMA mappings based on the mad_size of ib_mad_private.
6) Replace the use of sizeof and static defines as appropriate
7) Add appropriate casts for the MAD data when calling processing
functions.
