perf: Fix hypervisor sample reporting



cpumode bits are defined as such:

 #define PERF_RECORD_MISC_KERNEL                 (1 << 0)
 #define PERF_RECORD_MISC_USER                   (2 << 0)
 #define PERF_RECORD_MISC_HYPERVISOR             (3 << 0)

We need to compare against the complete value of cpumode,
otherwise hypervisor samples get incorrectly attributed as
userspace.
