[dpdk-dev] [PATCH] test/compress: fix size of test buffer

[Marko Kovacevic]

Changed size of test buffer to 100 to allow
qat to run compress unit-test,
qat_comp_process_response():
QAT intermediate buffer may be too small for output,
try configuring a larger size

Fixes: c1bbb613ce96 ("test/compress: add out of space test")
