iomap: don't make REQ_POLLED imply REQ_NOWAIT
As described in commit 2bc057692599 ("block: don't make REQ_POLLED imply
REQ_NOWAIT"), which fixed the same issue for the block device node, there
are valid cases to poll for I/O completion without REQ_NOWAIT.
Additionally, sing REQ_NOWAIT for file system writes is currently not
supported as file systems writes are not idempotent and would need a
retry of just the bio and not the entire operation to be fully supported.
Switch iomap to set REQ_POLLED and remove the now unused bio_set_polled
helper.
