Bug 1803109 - Discard blocks of data that are too big for two chunks. r=canaltinova

Currently, `ReserveAndPutRaw` allocates a second span even if the data would be too big for the chunk.
Here a second conditional is added to check if the block of data is too big in this scenario and silently discard the data if so.
