try to destroy relevant data structures, as well we kill a tasklet
which always result in following kernel warning.

pcmuio_detach() is called by the comedi core even if pcmuio_attach()
returned an error, so `dev->private` might be `NULL`.  Check for that
before dereferencing it.

pointer passed to `kfree()` is non-NULL, so remove that check.

In rxtx.c many calls to BBvCaculateParameter are not endian
corrected all calls here need to be endian corrected.

Correct the endian in BBvCaculateParameter.

In card.c: CARDvSetRSPINF pwPhyLen points to awLen and is
manually applied to abyData.  Because it is now endian
corrected put_unaligned is needed to correct it.

In rxtx.c remove were endian is corrected.

This allows to merge  BBvCalculateParameter *pwPhyLen,*pbyPhySrv
