staging: vt6655: Remove vif check from vnt_interrupt

A check for vif is made in vnt_interrupt_work. There is a small chance of leaving interrupt disabled while vif is NULL and the work hasn't been scheduled. Signed-off-by: Malcolm Priestley <[email protected]> CC: [email protected] # v4.2+ Signed-off-by: Greg Kroah-Hartman <[email protected]>
