[PATCH 3/3] media: ti: vpe: Fix the error code of devm_kzalloc() in vip_probe_slice()

[Felix Gu]

In vip_probe_slice(), the error check for devm_kzalloc() incorrectly
uses PTR_ERR_OR_ZERO() which returns 0 for NULL pointer.

Return -ENOMEM for devm_kzalloc() failure.

Fixes: fc2873aa4a21 ("media: ti: vpe: Add the VIP driver")
