exportfs: Remove EXPORT_OP_ASYNC_LOCK

Browse source 
Now that GFS2 and OCFS2 are signalling async ->lock() support with
FOP_ASYNC_LOCK and checks for support are converted, we can remove
EXPORT_OP_ASYNC_LOCK.

all of an inode's dirty data on last close. Exports that behave this
way should set EXPORT_OP_FLUSH_ON_CLOSE so that NFSD knows to skip
waiting for writeback when closing such files.
EXPORT_OP_ASYNC_LOCK - Indicates a capable filesystem to do async lock
requests from lockd. Only set EXPORT_OP_ASYNC_LOCK if the filesystem has
it's own ->lock() functionality as core posix_lock_file() implementation
has no async lock request handling yet. For more information about how to
indicate an async lock request from a ->lock() file_operations struct, see
fs/locks.c and comment for the function vfs_lock_file().
