[SCSI] qla4xxx: set device state as per Link UP and LINK DOWN

Link Down -> Mark all devices missing
 Previously, the driver took no action on a Link Down,
 and waited for the I/O on a dead connection to timeout
 in the firmware before marking the DDB missing.

Link Up -> Mark all devices online
 F/W will do auto login to all the devices only once.
 After that its the responsibility of the driver to
 relogin to devices whenever there is :
        * Any sort of connection failure or
        * KATO expires indicating target has logged out or
        * I/O times out etc.
