  -----------
  Keep pcsc reader flags when disconnected

When the reader is removed, the reader->flags are set to
SC_READER_REMOVED. card_detect_all() then frees resources and
sets slot->reader to NULL. During this, sc_card_disconnect()
is called, setting reader->flags to 0. In a subsequent call
to card_detect_all() with the reader still removed, the corresponding
slot is reclaimed, and slot->reader set back to the removed reader,
but slot->events is overwritten, which causes the C_WaitForSlot()
not to recognize event on the slot.
