Subject: [PATCH net-next] net: thunderx: Fix error return code in nicvf_open()

From: Wei Yongjun <weiyongjun1@...wei.com>

Fix to return a negative error code from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: 712c31853440 ("net: thunderx: Program LMAC credits based on MTU")
