Ilya Dryomov c77dd7b425 rbd: set max_segments to USHRT_MAX 
commit 21acdf45f4 upstream.

Commit d3834fefcf ("rbd: bump queue_max_segments") bumped
max_segments (unsigned short) to max_hw_sectors (unsigned int).
max_hw_sectors is set to the number of 512-byte sectors in an object
and overflows unsigned short for 32M (largest possible) objects, making
the block layer resort to handing us single segment (i.e. single page
or even smaller) bios in that case.

Fixes: d3834fefcf ("rbd: bump queue_max_segments")
