[PATCH 4.4 07/74] block: Initialize max_dev_sectors to 0

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Keith Busch <keith.busch@xxxxxxxxx>

commit 5f009d3f8e6685fe8c6215082c1696a08b411220 upstream.

The new queue limit is not used by the majority of block drivers, and
should be initialized to 0 for the driver's requested settings to be used.
