Peter Maydell 11b4666161 hw/block/fdc-isa: Assert that isa_fdc_get_drive_max_chs() found something
Coverity complains about an overflow in isa_fdc_get_drive_max_chs()
that can happen if the loop over fd_formats never finds a match,
because we initialize *maxc to 0 and then at the end of the
function decrement it.

This can't ever actually happen because fd_formats has at least
one entry for each FloppyDriveType, so we must at least once
find a match and update *maxc, *maxh and *maxs. Assert that we
did find a match, which should keep Coverity happy and will also
detect possible bugs in the data in fd_formats.

Resolves: Coverity CID 1547663
