drbd: remove macros using require_context
This require_context attribute originated in a proposed sparse patch by
Philipp Reisner back in 2008. Johannes Berg had a different solution to
a similar problem, and that patch "won" in the end; so the require_context
thing never got merged. The whole history can be read at [0].
DRBD kept using these annotations anyway for a while. Nowadays, on a
modern unmodified sparse, they obviously do nothing, and they are hardly
used anymore anyway.
So, just remove the definitions of these macros.
