[PATCH AUTOSEL for 4.15 074/189] nfp: fix error return code in nfp_pci_probe()

[Sasha Levin]

From: Wei Yongjun <weiyongjun1@xxxxxxxxxx>

[ Upstream commit e58decc9c51eb61697aba35ba8eda33f4b80552d ]

Fix to return error code -EINVAL instead of 0 when num_vfs above
limit_vfs, as done elsewhere in this function.

Fixes: 0dc786219186 ("nfp: handle SR-IOV already enabled when driver is probing")
