[PATCH 5.14 092/169] net: dsa: mt7530: correct ds->num_ports

[Greg Kroah-Hartman]

From: DENG Qingfang <dqfext@xxxxxxxxx>

commit 342afce10d6f61c443c95e244f812d4766f73f53 upstream.

Setting ds->num_ports to DSA_MAX_PORTS made DSA core allocate unnecessary
dsa_port's and call mt7530_port_disable for non-existent ports.

Set it to MT7530_NUM_PORTS to fix that, and dsa_is_user_port check in
port_enable/disable is no longer required.
