Alexander Motin db832c47fe Pack zrlock_t by 8 bytes
On FreeBSD this reduces this structure size from 64 to 56 bytes.
dnode_handle_t respectively reduces from 72 to 64 bytes. It sounds
like a waste to need 72 bytes to be able to relocate 808 bytes of
dnode_t, which relocation on FreeBSD is not even supported.
