Christoph Hellwig c3d8edb170 null_blk: don't cap max_hw_sectors to BLK_DEF_MAX_SECTORS
[ Upstream commit 9a9525de86 ]

null_blk has some rather odd capping of the max_hw_sectors value to
BLK_DEF_MAX_SECTORS, which doesn't make sense - max_hw_sector is the
hardware limit, and BLK_DEF_MAX_SECTORS despite the confusing name is the
default cap for the max_sectors field used for normal file system I/O.

Remove all the capping, and simply leave it to the block layer or
user to take up or not all of that for file system I/O.

Fixes: ea17fd354c ("null_blk: Allow controlling max_hw_sectors limit")
