net/mlx5: Fix addr's type in mlx5dr_icm_dm

clang errors when CONFIG_PHYS_ADDR_T_64BIT is not set:

drivers/net/ethernet/mellanox/mlx5/core/steering/dr_icm_pool.c:121:8:

Use phys_addr_t for addr's type in mlx5dr_icm_dm, which won't change
anything with 64-bit builds because phys_addr_t is u64 when
CONFIG_PHYS_ADDR_T_64BIT is set, which is always when CONFIG_64BIT is
set.
