Log:
  ix(4): Run {mod,msf,mbx,fdir,phy}_task in if_update_admin_status

  From Piotr:

  This patch introduces adapter->task_requests register responsible for
  recording requests for mod_task, msf_task, mbx_task, fdir_task and
  phy_task calls. Instead of enqueueing these tasks with
  GROUPTASK_ENQUEUE, handlers will be called directly from
  ixgbe_if_update_admin_status() while holding ctx lock.

  SIOCGIFXMEDIA ioctl() call reads adapter->media list. The list is
  deleted and rewritten in ixgbe_handle_msf() task without holding ctx
  lock. This change is needed to maintain data coherency when sharing
  adapter info via ioctl() calls.

  Patch co-authored by Krzysztof Galazka <krzysztof.galazka@intel.com>.
