qcacmn: Add support for checksum from FW for pktlog

If the FW sends a pktlog checksum in the FW ready event, store that in
pl_dev and use it as buf_hdr.version in the pktlog buffer header.

Also, use a new magic value to identify the checksum in the
buf_hdr.version field.

If the FW does not send the checksum, then the existing magic number
and standard version number would be maintained.
