file-posix: x-check-cache-dropped should default to false on reopen

The default value of x-check-cache-dropped is false. There's no reason
to use the previous value as a default in raw_reopen_prepare() because
bdrv_reopen_queue_child() already takes care of putting the old
options in the BDRVReopenState.options QDict.

If x-check-cache-dropped was previously set but is now missing from
the reopen QDict then it should be reset to false.
