7e30e6a6746b417c7e0dbc9af009560fbb63f336 block: vhdx - improve error message, and .bdrv_check implementation
If there is a dirty log file to be replayed in a VHDX image, it is
replayed in .vhdx_open(). However, if the file is opened read-only,
then a somewhat cryptic error message results.
This adds a more helpful error message for the user. If an image file
contains a log to be replayed, and is opened read-only, the user is
instructed to run 'qemu-img check -r all' on the image file.
Running qemu-img check -r all will cause the image file to be opened
r/w, which will replay the log file. If a log file replay is detected,
this is flagged, and bdrv_check will increase the corruptions_fixed
count for the image.
