hw/net/e1000e: Remove overwritten read handler for STATUS register

The STATUS register readop handler is initialized first with
the generic e1000e_mac_readreg() handler:

  2861 #define e1000e_getreg(x)    [x] = e1000e_mac_readreg
  2862 typedef uint32_t (*readops)(E1000ECore *, int);
  2863 static const readops e1000e_macreg_readops[] = {
  ....
  2919     e1000e_getreg(STATUS),

Then overwritten with the specific e1000e_get_status handler:

  3018     [STATUS]  = e1000e_get_status,

To avoid confusion, remove the overwritten initialization.
