net: ftgmac100: add missing error return code in ftgmac100_probe() 

[ Upstream commit 52af13a41489d7bbc1932d17583eff6e5fffc820 ]

The variables will be free on path err_phy_connect, it should
return error code, or it will cause double free when calling
ftgmac100_remove().

Fixes: bd466c3fb5 ("net/faraday: Support NCSI mode")
Fixes: 39bfab8844 ("net: ftgmac100: Add support for DT phy-handle property")
