Christoph Hellwig c67775cf0d iomap: allocate s_dio_done_wq for async reads as well 
[ Upstream commit 7fd8720dff ]

Since commit 222f2c7c6d14 ("iomap: always run error completions in user
context"), read error completions are deferred to s_dio_done_wq.  This
means the workqueue also needs to be allocated for async reads.

Fixes: 222f2c7c6d14 ("iomap: always run error completions in user context")
