Subject: [PATCH 2/2] ext4: make "norecovery" an alias for "noload"

Users on the list recently complained about differences across
filesystems w.r.t. how to mount without a journal replay.

In the discussion it was noted that xfs's "norecovery" option is
perhaps more descriptively accurate than "noload," so let's make
that an alias for ext4.

Also show this status in /proc/mounts

Queued, thanks.

I made a minor change to Documentation/filesystems/ext4.txt to make
"norecovery" be the first option, since we seem to be treating it as
the canonical option name in ext4_show_options().
