i40e: don't panic on VSI allocation failure
In some circumstances, the firmware may fail to allocate a VSI for a VF.
When this happens, the driver does not react well to the bad news and
has a panic attack.
To fix this problem, check the return value from i40e_alloc_vf_res and
don't try to configure the device further if it failed. Additionally,
explicitly clear the INIT bit when we free VF resources, so that this
bit will be in the proper state in the failure case, and won't blow up
elsewhere.
