Emmanuel Nicolet f03f34dc4e ps3disk: use the default segment boundary 
[ Upstream commit 720bc316690bd27dea9d71510b50f0cd698ffc32 ]

Since commit dcebd755926b ("block: use bio_for_each_bvec() to compute
multi-page bvec count"), the kernel will bug_on on the PS3 because
bio_split() is called with sectors == 0:

  kernel BUG at block/bio.c:1853!

  [ end trace 313fec760f30aa1f ]---

The problem originates from setting the segment boundary of the
request queue to -1UL. This makes get_max_segment_size() return zero
when offset is zero, whatever the max segment size. The test with
BLK_SEG_BOUNDARY_MASK fails and 'mask - (mask & offset) + 1' overflows
to zero in the return statement.

Not setting the segment boundary and using the default
value (BLK_SEG_BOUNDARY_MASK) fixes the problem.
