NFSD: Remove two unused NFSv4 constants

Browse Source 
Neither COMPOUND_SLACK_SPACE nor NFSD_COURTESY_CLIENT_TIMEOUT has
a remaining user. COMPOUND_SLACK_SPACE lost its last reference in
commit ea8d7720b2 ("nfsd4: remove redundant encode buffer size
checking"), which deleted the encode buffer-space check the macro
fed; the comment above it still describes that departed check.
NFSD_COURTESY_CLIENT_TIMEOUT is likewise unreferenced: the
courteous-server code expires clients through the laundromat's
reaper and conflict paths, never a fixed 24-hour timer.
