Fix for the two issues reported in HDFFV-10051:
(1) Repeated open/close of a compact dataset fails due to the
increment of ndims in the dataset structure for every open.
--This is done only for chunked dataset via H5D__chunk_set_sizes().
(2) layout "dirty" flag for a compact dataset is not reset
properly after flushing the data at dataset close.
--Reset the "dirty" flag before flushing the message to the object header
via H5O_msg_write().
Tested on moohan, kituo, platypus, ostrich, osx1010test, quail, emu.
