3.16.36-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Sebastian Ott <redacted>

commit b707c65ae70e24c47a0ce4a7279224ce8f0ffb7f upstream.

When we refuse a non REQ_TYPE_FS request in the build request function
we already hold the queue lock. Thus we must not call blk_end_request_all
but __blk_end_request_all.
