block: refactor generic_make_request
Move all the checks performed on a bio into a new helper, and call it as soon as bio is submitted even if it is a re-submission from ->make_request. We explicitly mark the new helper as beeing non-inlined as the stack usage for printing the block device name in the failure case is quite high and this a patch where we have to be extremely conservative about stack usage.
