nfsd: nfsd_file_acquire_local no longer returns GC'd nfsd_file

Browse Source 
Now that LOCALIO no longer leans on NFSD's filecache for caching open
files (and instead uses NFS client-side open nfsd_file caching) there
is no need to use NFSD filecache's GC feature.  Avoiding GC will speed
up nfsd_file initial opens.
