Without this change, case8 and case14 about DMA sequence test in fastRPC sanity test can not pass.

The steps to do fastRPC sanity test is:
1.download code
p4 login
export PATH="$PATH:/prj/qct/asw/qctss/linux/bin/vce"
vce.py view --base fastrpctest.common.1.0 --checkout=<username> --root .
2.compile command
chmod -R 777 ./fastrpc_tests && python3 ./fastrpc_tests/build_fastrpc_test.py -target=LE
3.run fastRPC test
fastrpc_tests_ReleaseG_push_LE.bat
adb shell fastrpc_tests -e (case number) -d 3
