David Howells cbaff0dfd1 afs: Fix file locking on R/O volumes to operate in local mode
[ Upstream commit b590eb41be766c5a63acc7e8896a042f7a4e8293 ]

AFS doesn't really do locking on R/O volumes as fileservers don't maintain
state with each other and thus a lock on a R/O volume file on one
fileserver will not be be visible to someone looking at the same file on
another fileserver.

Further, the server may return an error if you try it.

Fix this by doing what other AFS clients do and handle filelocking on R/O
volume files entirely within the client and don't touch the server.

Fixes: 6c6c1d63c243 ("afs: Provide mount-time configurable byte-range file locking emulation")
