Fix deadlock when ZVOLs are present and we are replacing dead component or
calling scrub when pool is in a degraded state. It will try to taste ZVOLs,

We can't simply skip provider based on their GEOM class, because ZVOL can have
providers build on top of it and we need to skip those as well.
We do it by asking for ZFS::iszvol attribute. Any ZVOL-based provider will give
us positive answer and we have to skip those providers.
This way we remove possibility to create ZFS pools on top of ZVOLs, but it is
not very useful anyway.
I believe deadlock is still possible in some very complex situations like when
we have MD provider on top of UFS file on top of ZVOL. When we try to replace
dead component in the pool mentioned ZVOL is based on, there might be a
deadlock when ZFS will try to taste MD provider. There is no easy way to detect
