hw/ide/atapi: Be explicit that assigning to s->lcyl truncates

In ide_atapi_cmd_reply_end() we calculate a 16-bit size, and then
assign its two halves to s->lcyl and s->hcyl like this:

           s->lcyl = size;
           s->hcyl = size >> 8;

Coverity warns that the first line here can overflow the
8-bit s->lcyl variable. This is true, and in this case we're
deliberately only after the low 8 bits of the value. The
code is clearer to both humans and Coverity if we're explicit
that we only wanted the low 8 bits, though.
