hw/sd/sdcard: Reset both start/end addresses on error

From the Spec "4.3.5 Erase":

  The host should adhere to the following command
  sequence: ERASE_WR_BLK_START, ERASE_WR_BLK_END and
  ERASE (CMD38).

  If an erase (CMD38) or address setting (CMD32, 33)
  command is received out of sequence, the card shall
  set the ERASE_SEQ_ERROR bit in the status register
  and reset the whole sequence.

Reset both addresses if the ERASE command occured
out of sequence (one of the start/end address is
not set).
