LTP crypto regressions noticed on linux next 20200621.

The common case for all tests is timeout after 15 minutes which
means tests got hung and LTP timers killed those test runs after
timeout.
The root cause of the failure is under investigation.

  ltp-crypto-tests:
    * af_alg02 - failed
    * af_alg05 - failed
  ltp-syscalls-tests:
    * keyctl07 - failed
    * request_key03 - failed

<trim>

Can you try reverting:

d13ef8e10756873b0a8b7cc8f230a2d1026710ea

The patch is titled "umh: fix processed error when UMH_WAIT_PROC is used"

Thanks for the investigation.
After reverting, two test cases got PASS out of four reported failure cases.
 ltp-crypto-tests:
     * af_alg02 - still failing - Hung and time out
     * af_alg05 - still failing - Hung and time out
  ltp-syscalls-tests:
     * keyctl07 - PASS
     * request_key03 - PASS

Please suggest the way to debug / fix the af_alg02 and af_alg05 failures.
