NFSD: Add an NFSD_FILE_GC flag to enable nfsd_file garbage collection
[ Upstream commit 4d1ea8455716ca070e3cd85767e6f6a562a58b1b ]
NFSv4 operations manage the lifetime of nfsd_file items they use by
means of NFSv4 OPEN and CLOSE. Hence there's no need for them to be
garbage collected.
Introduce a mechanism to enable garbage collection for nfsd_file
items used only by NFSv2/3 callers.
Note that the change in nfsd_file_put() ensures that both CLOSE and
DELEGRETURN will actually close out and free an nfsd_file on last
reference of a non-garbage-collected file.
