drbd: remove call to memset before free device/resource/connection
[ Upstream commit 6e7b854e4c1b02dba00760dfa79d8dbf6cce561e ]
This revert c2258ffc56f2 ("drbd: poison free'd device, resource and
connection structs"), add memset is odd here for debugging, there are
some methods to accurately show what happened, such as kdump.
