[Intel-wired-lan] [PATCH] fm10k:Fix error handling in the function fm10k_probe

[Nicholas Krause]

This fixes error handling in the function fm10k_probe to properly
if the call to the function fm10k_iov_configure has failed by
returning a error code before jumping to a new goto label,
fm10k_iov_configure to clean up previously allocated resources
between this goto label and the previous goto label before finally
returning the error code to the callers of the function fm10k_probe
