nfsd: allow filecache to hold S_IFDIR files
The filecache infrastructure will only handle S_IFREG files at the
moment. Directory delegations will require adding support for opening
S_IFDIR inodes.
Plumb a "type" argument into nfsd_file_do_acquire() and have all of the
existing callers set it to S_IFREG. Add a new nfsd_file_acquire_dir()
wrapper that nfsd can call to request a nfsd_file that holds a directory
open.
For now, there is no need for a fsnotify_mark for directories, as
CB_NOTIFY is not yet supported. Change nfsd_file_do_acquire() to avoid
allocating one for non-S_IFREG inodes.
