Reference_tracking_enable should be a module param

Browse Source 
To make use of zfs_refcount_held tunable it should be a module 
parameter in open-zfs.  Also, since the macros will auto-generate OS 
specific tunables, removed the existing zfs_refcount_held reference 
in module/os/freebsd/zfs/sysctl_os.c.
