Andriy Gapon 9d200697d7 zfsboot: simplify probe_drive() a little bit
The first discovered pool, whether it covers the whole boot disk or not,
is going to be first in zfs_pools list.  So there is no need at all
for spapp parameter.

This commit also fixes a bug where NULL would be assigned to NULL
pointer when probe_drive was called  with the spapp parameter of NULL.
