net/mlx5: remove redundancy in MR file
This patch remove two redundant things from MR file:
1. mr_find_contig_memsegs_data structure which is moved to common file
before.
2. External memory mechanism - mlx5_tx_update_ext_mp function.
Since commit [1] which added support for DMA map and unmap, external
mem must be configured by the user using rte_mem_map function and no
need to handle this in pmd.
