scsi: qla2xxxx: avoid type mismatch in comparison

A recent bug fix added code that does

        bool logged_out = (status & 0xFFFF);
        if (logged_out == CTIO_PORT_LOGGED_OUT)
		...

This looks wrong because we are comparing a boolean with an
integer constant, ang gcc warns about it accordingly:

drivers/scsi/qla2xxx/qla_target.c: In function 'qlt_do_ctio_completion':
drivers/scsi/qla2xxx/qla_target.c:3587:20: warning: comparison of constant '41' with boolean expression is always false [-Wbool-compare]
        (logged_out == CTIO_PORT_LOGGED_OUT) ?

The correct fix is presumably to make that variable an 'int'.
