Add a workaround.

Now, if we have for example: ad0s1 ad0s1c ad2s1 ad2s1c and we will try
to do: gconcat label foo /dev/ad0s1 /dev/ad2s1 we'll get a panic:
panic: spoiled but dcr = 1
for inside of geom_slice class, backtrace shows:
g_access()
g_slice_access()
g_access()
g_concat_read_metadata()
We need to get a proper fix for this race before geom(8) will be committed.
