HBASE-27019 Minor compression performance improvements (#4420) 

TRACE level logging is expensive enough to warrant removal. They were
useful during development but are now just overhead.

Also we unnecessarily create new compressor and decompressor instances
in the reset() methods for the Aircompressor and Lz4 codecs. Remove.
