Subject: [PATCH] LINUX: Remove test for DCACHE_NFSFS_RENAMED

The symbol DCACHE_NFSFS_RENAMED has existed in Linux for a long time,
well before the 2.6 version series. This is before our minimum supported
Linux kernel version of 2.6.18, so we don't need to check for it
anymore. Remove the configure test, and remove all references to
HAVE_DCACHE_NFSFS_RENAMED (assuming it's always true).

Keep the afs_linux_clear_nfsfs_renamed() et al abstractions, since they
may help keep the code more readable, but fix their formatting while
we're here.
