[PATCH net-next 14/14] net: enetc: use kzalloc_flex() for enetc_psfp_gate allocation

[wei.fang@oss.nxp.com]

From: Wei Fang <wei.fang@nxp.com>

Replace the open-coded struct_size() + kzalloc() pattern with the
kzalloc_flex() helper when allocating struct enetc_psfp_gate. This
removes the intermediate entries_size local variable and makes the
allocation site more concise.
