namei: IH_REALLYCLOSE special inode on delete
When we delete a special inode, we should IH_REALLYCLOSE it, to ensure
no other cached file handles are open for that special inode. However,
currently PurgeHeader_r does this, and then IH_DECs the special
inodes. On namei, calling IH_DEC on a special inode causes the inode
to be opened, so we create a cached file handle right after we closed
all cached file handles for that inode with IH_REALLYCLOSE.
Making namei IH_DEC not open an FdHandle_t for the given file is
non-trivial, at least when dec'ing the linktable. So instead, just
make namei IH_DEC itself issue the IH_REALLYCLOSE right before the
actual unlink() call.
With this, we can keep the cached file handle open for special inodes
until right before they are actually deleted, so we don't issue extra
unnecessary open()s and close()s.
