CUDA component: multiple reads results in erroneous values

The CUDA11 portion of the cuda component is returning erroneous values when multiple PAPI_read operations are called.

Sample expected output:

PAPI Started!
Launching CUDA code
After PAPI stop
    cuda:::sm__warps_launched.sum:device=0,1568

‌

Sample erroneous outputs:

PAPI Started!
After first read, no kernel launched
    cuda:::sm__warps_launched.sum:device=0,0
Launching CUDA code
After PAPI stop
    cuda:::sm__warps_launched.sum:device=0,784

PAPI Started!
Launching CUDA code
After first read, kernel launched
    cuda:::sm__warps_launched.sum:device=0,1568
After PAPI stop
    cuda:::sm__warps_launched.sum:device=0,2352

PAPI Started!
After first read, no kernel launched
    cuda:::sm__warps_launched.sum:device=0,0
Launching CUDA code
After second read, kernel launched
    cuda:::sm__warps_launched.sum:device=0,784
After PAPI stop
    cuda:::sm__warps_launched.sum:device=0,1306

PAPI Started!
After first read, no kernel launched
    cuda:::sm__warps_launched.sum:device=0,0
Launching CUDA code
After second read, kernel launched
    cuda:::sm__warps_launched.sum:device=0,784
After third read, no kernel launched
    cuda:::sm__warps_launched.sum:device=0,1306
After forth read, no kernel launched
    cuda:::sm__warps_launched.sum:device=0,1698
After PAPI stop
    cuda:::sm__warps_launched.sum:device=0,2012
