[PATCH 1/2] mdadm: set swapuuid in all handlers

[Mariusz Tkaczyk <mariusz.tkaczyk@linux.intel.com>]

It is not set, so it should be 0 but it may vary on compilation
settings. Set it always to 0.

metadata should care to set UUID and read in proper endianness so it
doesn't follow super1 concept of swapuuid to depend on endianness.

It is not an attempt to fix endianness issues.
