Subject: [LTP] [PATCH] testcases:Fix the failure of shell script to get path

For example, in the file testcases/kernel/controllers/cpuset/cpuset_funcs.sh, if the path is obtained by
find "$CPUSET" -type d | sort | sed -n '2,$p' | tac | while read subdir, the escaped characters will be lost,
and by adding the -r option, the escaped characters will be kept as they are without escaping
The errors are as follows:
/opt/ltp/testcases/bin/cpuset_funcs.sh:line178: /dev/cpuset/machine.slice/machine-qemux2d157x2dzhx2dsxf.scope/vcpu7/tasks: The file or directory is not available
rmdir: delete '/dev/cpuset/machine.slice/machine-qemux2d157x2dzhx2dsxf.scope/vcpu7' Failure: The file or directory is not available
cpuset_memory_pressure 1 TFAIL: Couldn't remove subdir -
/opt/ltp/testcases/bin/cpuset_funcs.sh:line178: /dev/cpuset/machine.slice/machine-qemux2d157x2dzhx2dsxf.scope/vcpu7/tasks: The file or directory is not available
