[onert/acl-cl] Fullyconnected hybrid model test fail

[hseok-oh]

After bug patch on #9926, fullyconnected/hybrid model test fail.

Fail release build, acl-cl backend on ubuntu 18.04
Passed on 20.04 (my local environment).

Maybe too large size FC operation makes quantization error.

Number of all operator types          :    1
  FULLY_CONNECTED                     :    1
Number of all operators               :    1

Expected TOTAL  memory: 2.6M
Expected FILLED memory: 2.5M

But it is strange why there is not error on debug build.

It is resolved by ARMCompute version up. #14454
