xen/blkback: move blkif_get_x86_*_req() into blkback.c

There is no need to have the functions blkif_get_x86_32_req() and
blkif_get_x86_64_req() in a header file, as they are used in one place
only.

So move them into the using source file and drop the inline qualifier.

While at it fix some style issues, and simplify the code by variable
reusing and using min() instead of open coding it.

Instead of using barrier() use READ_ONCE() for avoiding multiple reads
of nr_segments.
