    zfs: drop duplicate `vfs.zfs.metaslab.condense_pct` sysctl
    
    `metaslab.c` already registers this tunable via `ZFS_MODULE_PARAM`, so the
    `SYSCTL_UINT` here is a second registration of the same leaf. This
    resulted in messages like:
    
    ```
    sysctl_register_oid: can't re-use a leaf (vfs.zfs.metaslab.condense_pct)
    ```
    
    Remove the duplicate sysctl registration, as upstream (OpenZFS) did.
