block/mirror: Revive dead yielding code
mirror_iteration() is supposed to wait if the current chunk is subject
to a still in-flight mirroring operation. However, it mixed checking
this conflict situation with checking the dirty status of a chunk. A
simplification for the latter condition (the first chunk encountered is
always dirty) led to neglecting the former: We just skip the first chunk
and thus never test whether it conflicts with an in-flight operation.
To fix this, pull out the code which waits for in-flight operations on
the first chunk of the range to be mirrored to settle.
