[PATCH mlx5-next 1/2] net/mlx5: Drop redundant esw_cap, reuse e_switch_cap

[Tariq Toukan <tariqt@nvidia.com>]

From: Shay Drory <shayd@nvidia.com>

esw_manager_vport_number{,_valid} and merged_eswitch were read through a
separate mlx5_ifc_esw_cap_bits struct, but these bits live in the
e-switch capability that mlx5_ifc_e_switch_cap_bits already describes
(both overlay the same QUERY_HCA_CAP op_mod 0x9 output).

Add esw_manager_vport_number{,_valid} to mlx5_ifc_e_switch_cap_bits at
the same offsets, drop the redundant mlx5_ifc_esw_cap_bits and its
hca_cap_union member, and switch the only user (hws/cmd.c) to
capability.e_switch_cap.
