[LTP] [PATCH v2 2/2] controllers/cpuacct: fix rmdir failures on early test abort

[Krzysztof Kozlowski]

The "testpath" variable is assigned at the end of setup(), so if test
exits early, the "rmdir $testpath" is wrong:

    cpuacct 1 TCONF: not enough of memory on this system (less than 3840 MB)
    cpuacct 1 TINFO: removing created directories
    rmdir: missing operand
    Try 'rmdir --help' for more information.
