i40e: Remove scheduling while atomic possibility

i40e: Remove scheduling while atomic possibility

In some occasions task held spinlock (mac_filter_hash_lock),
while being rescheduled due to admin queue mutex_lock.  The struct
i40e_spinlock asq_spinlock, which later expands to struct mutex
spinlock.  Moved i40e_aq_set_vsi_multicast_promiscuous(),
i40e_aq_set_vsi_unicast_promiscuous(),
i40e_aq_set_vsi_mc_promisc_on_vlan(), and
i40e_aq_set_vsi_uc_promisc_on_vlan() outside of atomic context.  Without
this patch there is a race condition, which might result in scheduling
while in atomic context.  The race condition is between the thread, which
holds mac_filter_hash_lock, while trying to acquire an admin queue mutex
and a thread, which already has said admin queue mutex. The thread, which
holds spinlock, fails to acquire the mutex, which causes this thread to
sleep.
