dm bufio: fix error code in dm_bufio_write_dirty_buffers()
We should be returning normal negative error codes here. The "a"
variables comes from &c->async_write_error which is a blk_status_t
converted to a regular error code.
In the current code, the blk_status_t gets propogated back to
pool_create() and eventually results in an Oops.
Fixes: 4e4cbee93d
("block: switch bios to blk_status_t")
