ice_phy_conf_link() allocates the PHY capabilities buffer and only
then validates hw->port_info.
If hw->port_info is NULL,it returns directly without freeing
PHY capabilities buffer causing the buffer leak.

This patch fixes the issue by moving the hw->port_info NULL check
above the PHY capabilities buffer allocation.

Fixes: 36afbc269081 ("net/ice: support link speed change")
Cc: stable@dpdk.org
