A few fixes of callback typecasting (for the upcoming ClangCFI)
* zio: avoid callback typecasting * zil: avoid zil_itxg_clean() callback typecasting * zpl: decouple zpl_readpage() into two separate callbacks * nvpair: explicitly declare callbacks for xdr_array() * linux/zfs_nvops: don't use external iput() as a callback * zcp_synctask: don't use fnvlist_free() as a callback * zvol: don't use ops->zv_free() as a callback for taskq_dispatch() Reviewed-by: Brian Behlendorf <[email protected]> Reviewed-by: Mark Maybee <[email protected]> Signed-off-by: Alexander Lobakin <[email protected]> Closes #12260
