The ihashsize option should remain so that filesystems with
this set don't fail to mount. Ignore the mount option value
and issue a deprecation warning to syslog.
Update the ihashsize mount option documentation to indicate this
behaviour. Update the ikeep/noikeep mount option documentation
while we are there.
