[PATCH 07/11] dasd: don't set the discard_alignment queue limit

[Christoph Hellwig]

The discard_alignment queue limit is named a bit misleading means the
offset into the block device at which the discard granularity starts.
Setting it to PAGE_SIZE while the discard granularity is the block size
that is smaller or the same as PAGE_SIZE as done by dasd is mostly
harmless but also useless.
