net/mlx5: E-switch, correct stale VF/PF wording in esw-allowed comments

Browse Source 
mlx5_esw_hold() and mlx5_eswitch_unblock_ipsec() bail out on
!mlx5_esw_allowed(), and their comments explained that as "a VF has no
eswitch" / "core dev is not a PF". New FW will let a VF act as a nested
e-switch manager - such a VF has an eswitch and passes
mlx5_esw_allowed() - so that equivalence no longer holds. Reword the
comments to describe the actual condition, the device is not an e-switch
manager, with no functional change.
