[PATCH 4/5] libxg: drop dead assignment to "rc" from xc_cpuid_apply_policy()

[Jan Beulich]

"rc" is written immediately below the outer if(). Fold the remaining two
if()s.

Coverity ID: 1532320
Fixes: 685e922d6f30 ("tools/libxc: Rework xc_cpuid_apply_policy() to use 
{get,set}_cpu_policy()")

The code in question was subsequently moved by 54463aa79dac ("x86/hvm:
