md/raid5: fix raid5_run() to return error when log_init() fails

Browse source

[ Upstream commit 2d9f7150ac ]

Since commit f63f17350e ("md/raid5: use the atomic queue limit
update APIs"), the abort path in raid5_run() returns 'ret' instead of
-EIO. However, if log_init() fails, 'ret' is still 0 from the previous
successful call, causing raid5_run() to return success despite the
failure.

Fix this by capturing the return value from log_init().
