Richard Yao c9e39da9a4 Use rw_tryupgrade() in dmu_bonus_hold_by_dnode() ...

When dn->dn_bonus == NULL, dmu_bonus_hold_by_dnode() will unlock its
read lock on dn->dn_struct_rwlock and grab a write lock. This can be
micro-optimized by calling rw_tryupgrade().

Linux will not benefit from this since it does not support rwlock
upgrades, but FreeBSD will.
