Junbeom reported that synchronous reads could hit unintended EIOs under memory pressure due to incorrect error propagation in z_erofs_decompress_queue(), where earlier physical clusters in the same decompression queue may be served for another readahead. This patch addresses the issue by decompressing each physical cluster independently as long as disk I/Os succeed, rather than being impacted by the error status of previous physical clusters in the same queue. Happy Xmas and new year in advance!
