ixgbevf: don't release the soft entries
When the ixgbevf driver is opened the request to allocate MSIX irq
vectors may fail. In that case the driver will call ixgbevf_down()
which will call ixgbevf_irq_disable() to clear the HW interrupt
registers and calls synchronize_irq() using the msix_entries pointer in
the adapter structure. However, when the function to request the MSIX
irq vectors failed it had already freed the msix_entries which causes
an OOPs from using the NULL pointer in synchronize_irq().
The calls to pci_disable_msix() and to free the msix_entries memory
should not occur if device open fails. Instead they should be called
during device driver removal to balance with the call to
pci_enable_msix() and the call to allocate msix_entries memory
during the device probe and driver load.
