Fixes for SNPRINTF_BLKPTR with encrypted BP's

Browse Source 
mdb doesn't have dmu_ot[], so we need a different mechanism for its
SNPRINTF_BLKPTR() to determine if the BP is encrypted vs authenticated.

Additionally, since it already relies on BP_IS_ENCRYPTED (etc),
SNPRINTF_BLKPTR might as well figure out the "crypt_type" on its own,
rather than making the caller do so.
