pc-bios/s390-ccw: virtio_load_direct() can't load max number of sectors
The number of sectors to read is given by the last 16 bit of rec_list2.
1 is added in order to get to the real number of sectors to read (0x0000
-> read 1 block). For now, the maximum number (0xffff) led to 0 sectors
being read.
This fixes a bug where a large initrd (62MB) could not be ipled anymore.
