cpupower: Remove unused pscur variable.

mainline inclusion
from mainline-5.12-rc1-dontuse
commit 1421de79
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I4QQWF



--------------------------------

The pscur variable is set but not uused, just remove it.

This may have previsously been set to validate the MSR_AMD_PSTATE_STATUS
MSR. With the addition of the CPUPOWER_CAP_AMD_HW_PSTATE cap flag this
is no longer needed since the cpuid bit to enable this cap flag also
validates that the MSR_AMD_PSTATE_STATUS MSR is present.
