zfs-module-parameters(5): add all missing items
I ran a report against the output of `modinfo zfs.ko`. This commit adds everything missing and corrects a few renamed module parameters. Specifically: * zfs_checksums_per second renamed inad796b8a3
* vdev_ms_count_limit renamed inc853f382d
Also fixes some variable type inconsistencies (unsigned int => uint) Reviewed-by: George Amanakis <gamanakis@gmail.com> Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: DHE <git@dehacked.net> Closes #9809
