Cache bypass: remove ifdefs under src/afs/LINUX24

Cache bypass: remove ifdefs under src/afs/LINUX24

Same as commit 9657695d34badaac654227be8c731a1512f2106b, but for
LINUX24. Remove the AFS_CACHE_BYPASS references in LINUX24, since it
is always enabled. Also remove messages about a "cache bypass patched
module".
