i40e: fix i40e_setup_misc_vector() error handling

Browse Source 
[ Upstream commit c86c00c6935505929cc9adb29ddb85e48c71f828 ]

Add error handling of i40e_setup_misc_vector() in i40e_rebuild().
In case interrupt vectors setup fails do not re-open vsi-s and
do not bring up vf-s, we have no interrupts to serve a traffic
anyway.
