RFR: 8253050: jfr disassemble command processes --max-chunks incorrectly

[Ekaterina Vergizova]

Hello,

could I have a review of this fix.

JBS: https://bugs.openjdk.java.net/browse/JDK-8253050
Webrev: https://cr.openjdk.java.net/~apetushkov/8253050/webrev.00/

The problem is caused by Disassemble.combineChunkSizes() implementation that checks maxChunks after incrementation of fileSize, therefore the first output file has extra chunk.

Testing:
jdk/jdk/jfr/*

Thanks,
Ekaterina
