perf kmem: Resolve kernel symbols again
Due to the assumption in perf_session__new that the kernel maps would be
created using the fake PERF_RECORD_MMAP event in a perf.data file 'perf
kmem --stat caller', that doesn't have such event, ends up not being
able to resolve the kernel addresses.
Fix it by calling perf_session__create_kernel_maps() in __cmd_kmem().
