Subject: [PATCH -next] net: ethernet: ti: cpsw: fix error return code in cpsw_set_channels()

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

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

Fixes: ce52c744574b ("net: ethernet: ti: cpsw: add ethtool channels support")
