[SAMBA 4 / NETLOGON] Modify type of SAM contexts

In the SAMBA 4 DCE/RPC NETLOGON server the SAM context references have generally
the type "void *". But we know that those context objects are based on the "struct
ldb_context" type. We've always to cast for using a SAM/LDB call.
This I didn't find very appealing and so I assigned the right (detailed) type to each "sam_ctx".
Therefore, the casts could disappear.

Also this change is only cosmetic.
