Roland Dreier e328d41082 vmxnet3: Consistently disable irqs when taking adapter->cmd_lock 
Using the vmxnet3 driver produces a lockdep warning because
vmxnet3_set_mc(), which is called with mc->mca_lock held, takes
adapter->cmd_lock.  However, there are a couple of places where
adapter->cmd_lock is taken with softirqs enabled, lockdep warns that a
softirq that tries to take mc->mca_lock could happen while
adapter->cmd_lock is held, leading to an AB-BA deadlock.

I'm not sure if this is a real potential deadlock or not, but the
simplest and best fix seems to be simply to make sure we take cmd_lock
with spin_lock_irqsave() everywhere -- the places with plain spin_lock
just look like oversights.

The full enormous lockdep warning is:

 =========================================================
 [ INFO: possible irq lock inversion dependency detected ]
 2.6.39-rc6+ #1
 ---------------------------------------------------------
 ifconfig/567 just changed the state of lock:
  (&(&mc->mca_lock)->rlock){+.-...}, at: [<ffffffff81531e9f>] mld_ifc_timer_expire+0xff/0x280
 but this lock took another, SOFTIRQ-unsafe lock in the past:
  (&(&adapter->cmd_lock)->rlock){+.+...}

 and interrupts could create inverse lock ordering between them.

 other info that might help us debug this:
