Subject: qlcnic: fix unchecked return value
From: Pan Bian <bianpan2016@163.com>
[ Upstream commit 91ec701a553cb3de470fd471c6fefe3ad1125455 ]
Function pci_find_ext_capability() may return 0, which is an invalid
address. In function qlcnic_sriov_virtid_fn(), its return value is used
without validation. This may result in invalid memory access bugs. This
patch fixes the bug.
