RDMA/rxe: Prevent double freeing rxe_map_set()
The same rxe_map_set could be freed twice:
rxe_reg_user_mr()
-> rxe_mr_init_user()
-> rxe_mr_free_map_set() # 1st
-> rxe_drop_ref()
...
-> rxe_mr_cleanup()
-> rxe_mr_free_map_set() # 2nd
Follow normal convection and put resource cleanup either in the error
unwind of the allocator, or the overall free function. Leave the object
unchanged with a NULL cur_map_set on failure and remove the unncessary
free in rxe_mr_init_user().
