During VF deallocation, we need to lock out the VF reset code. However, we cannot depend on simply masking the interrupt, as this does not lock out the service task, which can still call the reset routine. Instead, leave the interrupt enabled, but add locking around the VF disable and reset routines. For the disable code, we wait to get the lock, as the reset code will take a finite amount of time to run. For the reset code, we just return if we fail to get the lock. Since we know that the VFs are being disabled, we don't need to handle the reset. This fixes a panic when disabling SR-IOV.
