This patch refactors MKEY usage such as its life cycle will be as of the migration file instead of allocating/destroying it upon each SAVE/LOAD command. This is a preparation step towards the PRE_COPY series where multiple images will be SAVED/LOADED. We achieve it by having a new struct named mlx5_vhca_data_buffer which holds the mkey and its related stuff as of sg_append_table, allocated_length, etc. The above fields were taken out from the migration file main struct, into mlx5_vhca_data_buffer dedicated struct with the proper helpers in place. For now we have a single mlx5_vhca_data_buffer per migration file. However, in coming patches we'll have multiple of them to support multiple images.
