qa/tasks/rbd: don't wait for krbd symlink to be created/removed

Commit 3754c665a11e (":qa/tasks/rbd: test qemu on top of rbd
encryption") broke dev_create() for krbd by messing up the "wait
for the symlink to be created by udev" loop.  The rbd tool has been
synchronizing with udev internally since 2014, so rather than fixing
let's just drop it.
