John Baldwin 926f079146 Don't look for GPT primary and secondary tables on a disk unless we have ...

a valid PMBR.  Without this fix, if label a disk with a GPT, then relabel
it with an MBR the GPT tables are still present.  If you then try to create
a GPT with 'gpt create', gpt(8) will fail to open the device because the
partitions in the stale GPT overlap with the slices in the MBR.
