[PATCH net-next v2 2/3] net: stmmac: fpe: Add missing return in stmmac_fpe_init()

From: Nazim Amirul <redacted>

When FPE is not supported by the driver, stmmac_fpe_init() prints a
warning but falls through into the pmac_enabled initialization, which
should only be reached on supported hardware. Add the missing return
to prevent this.
