[PATCH AUTOSEL 5.7 199/388] phy: ti: j721e-wiz: Fix some error return code in wiz_probe()

[Sasha Levin]

From: Wei Yongjun <weiyongj...@huawei.com>

[ Upstream commit e2ae8bca494481a9f38fcd1d52943ac04e654745 ]

Fix to return negative error code from some error handling
cases instead of 0, as done elsewhere in this function.

Fixes: 091876cc355d ("phy: ti: j721e-wiz: Add support for WIZ module present in 
TI J721E SoC")
