qlcnic: check pci_reset_function result
[ Upstream commit 7573099e10ca69c3be33995c1fcd0d241226816d ]
Static code analyzer complains to unchecked return value.
The result of pci_reset_function() is unchecked.
Despite, the issue is on the FLR supported code path and in that
case reset can be done with pcie_flr(), the patch uses less invasive
approach by adding the result check of pci_reset_function().
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixes: 7e2cf4feba05 ("qlcnic: change driver hardware interface mechanism")
