[PATCH v3 1/2] zbd: add missing client/server support for option max_open_zones

[Niklas Cassel <Niklas.Cassel@wdc.com>]

From: Niklas Cassel <niklas.cassel@wdc.com>

Ensure that we convert the max_open_zones option for client/server.

Use __cpu_to_le32()/__le32_to_cpu() rather than
cpu_to_le32()/le32_to_cpu(), since max_open_zones is defined
as int rather than unsigned int in thread_options.h.
