iflib: Initialize the VFLR task unconditionally

The VFLR task was initialized only from drivers MSI-X interrupt
assignment paths.  ixl's legacy interrupt handler can nevertheless defer
VFLR work, leaving an uninitialized task.  Even with MSI-X, the admin
interrupt was established before the task was initialized.

Initialize it alongside the other private tasks.  The existing detach
check and private-taskqueue drains then cover its lifecycle for every
interrupt mode and registration failure.
