[PATCH/resend] constify more dcache.h inlined helpers.

[NeilBrown]

Many of the inlines in dcache.h were changed to accept
const struct pointers in commit f0d3b3ded999 ("constify dcache.c
inlined helpers where possible").
This patch allows 'const' in a couple that were added since then.

Hi Al,
 I still don't see this in your tree, despite you saying on Oct 20th
 that it had been applied.  So I thought it might be a good time to
 resend.

Thanks,
NeilBrown
