[PATCH 1/1] rumpdisk: wrap usage of DEV_FLUSH_CAHCE in ifdef

[dnietoc]

From: Diego Nieto Cid <dnie...@gmail.com>

  * rumpdisk/block-rump.c: following the pattern at libstore/device.c, where
    dev_sync conditionally uses DEV_FLUSH_CACHE, the switch case for
    DEV_FLUSH_CACHE in block-rump.c is wrapped in ifdef.
