Second call of sysctl() is used to gather a proper size of a memory chunk
needed to hold the GEOM tree. At this point, pointer 'p' has an improper
value (as it was used previously), and we're getting EFAULT. Fix this
functionality by passing NULL instead of 'p'.
This fixes mdconfig(8) -l output with high number of md(4) devices.
