net/mlx5: E-switch, Extend eswitch enable to handle num_vfs change

Subsequent patch protects eswitch mode changes across sriov and devlink
interfaces. It is desirable for eswitch to provide thread safe eswitch
enable and disable APIs.
Hence, extend eswitch enable API to optionally update num_vfs when
requested.

In subsequent patch, eswitch num_vfs are updated after all the eswitch
users eswitch drops its reference count.
