RDMA/siw: Fix 64/32bit pointer inconsistency 

Fixes improper casting between addresses and unsigned types.
Changes siw_pbl_get_buffer() function to return appropriate
dma_addr_t, and not u64.

Also fixes debug prints. Now any potentially kernel private
pointers are printed formatted as '%pK', to allow keeping that
information secret.

Fixes: d941bfe500be ("RDMA/siw: Change CQ flags from 64->32 bits")
Fixes: b0fff7317b ("rdma/siw: completion queue methods")
Fixes: 8b6a361b8c ("rdma/siw: receive path")
Fixes: b9be6f18cf ("rdma/siw: transmit path")
Fixes: f29dd55b02 ("rdma/siw: queue pair methods")
Fixes: 2251334dca ("rdma/siw: application buffer management")
Fixes: 303ae1cdfd ("rdma/siw: application interface")
Fixes: 6c52fdc244 ("rdma/siw: connection management")
Fixes: a531975279 ("rdma/siw: main include file")
