Ned Bass 73aac4aa41 Some additional send stream validity checking 
Check in the DMU whether an object record in a send stream being
received contains an unsupported dnode slot count, and return an
error if it does. Failure to catch an unsupported dnode slot count
would result in a panic when the SPA attempts to increment the
reference count for the large_dnode feature and the pool has the
feature disabled. This is not normally an issue for a well-formed
send stream which would have the DMU_BACKUP_FEATURE_LARGE_DNODE flag
set if it contains large dnodes, so it will be rejected as
unsupported if the required feature is disabled. This change adds a
missing object record field validation.

Add missing stream feature flag checks in
dmu_recv_resume_begin_check().

Consolidate repetitive comment blocks in dmu_recv_begin_check().

Update zstreamdump to print the dnode slot count (dn_slots) for an
object record when running in verbose mode.
