lib/accel: name crc function param for consistency

Browse Source 
We've always used `dst` as the destination for CRC result, with
the recent addition of a copy_CRC API `dst` was needed for the
copy destination and `crc_dst` was used for the CRC.  This
patch just makes all the CRC functions use `crc_dst` to avoid
confusion.  The accel_task struct also has a `crc_dst1 field,
that will be used consistently in the next patch.
