description:
Fix some problems found by KUBSan:
- Set TQSM and RQSM (TX/RX queue statistics mapping) correctly.
- Set IVAR (Interrupt Vector Allocation Register) correctly in
  ixgbe_set_ivar().
- Define IXGBE_KRM_LINK_CTRL_1_TETH_AN_RESTART correctly. This macro is used
  in ixgbe_restart_an_internal_phy_x550em().
- Define IXGBE_KRM_TX_COEFF_CTRL_1_OVRRD_EN correctly. This macro is used
  in ixgbe_setup_ixfi_x550em_x().
- Define IXGBE_SB_IOSF_CTRL_BUSY correctly. This macro is used in
  ixgbe_iosf_wait() (X550EM only).
