ide: Correct the CHS 'cyls_max' limit to be 65535

In b7eb0c9:
  hw/block-common: Factor out fall back to legacy -drive cyls=...
'blkconf_geometry()' was introduced, factoring out CHS limit validation
code that was repeated in ide, scsi, virtio-blk.

The original IDE CHS limit prior b7eb0c9 was 65535,16,255 (as per ATA
CHS addressing).
However the 'cyls_max' argument passed to 'blkconf_geometry' in the
ide_dev_initfn case was accidentally set to 65536 instead of 65535.

Fix, providing the correct 'cyls_max'.
