From: Chiara Meiohas <cmeiohas@nvidia.com>

phys_port_cnt of the IB device must be initialized before calling
ib_device_set_netdev().

Previously, phys_port_cnt was initialized in the mlx5_ib init function.
Remove this initialization to allow setting it separately, providing
the flexibility to call ib_device_set_netdev before registering the
IB device.
