Qu Wenruo aa660331c0 btrfs: re-introduce 'norecovery' mount option 
commit 440861b1a0 upstream.

Although 'norecovery' mount option was marked as deprecated for a long
time and a warning message was printed during the deprecation window,
it's still actively utilized by several projects that need a safer way
to mount a btrfs without any writes.

Furthermore this 'norecovery' mount option is supported by other major
filesystems, which makes it less clear what's our motivation to remove
it.

Re-introduce the 'norecovery' mount option, and output a message to recommend
'rescue=nologreplay' option.
