zfs_log: make zfs_immediate_write_sz uint

Browse Source 
Likely it's only int64 for comparison with ssize_t, which is signed.
However, it would make no sense for it to be less than 0 or greater than
4G, so making it a regular uint will make it safe for comparison and
remove the only S64 tunable in core.
