perf stat: fix NULL pointer reference bug with event unit
This patch fixes a problem with the handling of the newly introduced
optional event unit. The following cmdline caused a segfault:
$ perf stat -e cpu/event-0x3c/ ls
This patch fixes the problem with the default setting for alias->unit
which was eventually causing the segfault.
