[Xen-devel] [Patch] Call sched_destroy_domain before cpupool_rm_domain.

[Nathan Studer <nate.studer@xxxxxxxxxxxxxxx>]

From: Nathan Studer <nate.studer@xxxxxxxxxxxxxxx>

The domain destruction code, removes a domain from its cpupool
before attempting to destroy its scheduler information.  Since
the scheduler framework uses the domain's cpupool information
to decide on which scheduler ops to use, this results in the
the wrong scheduler's destroy domain function being called
when the cpupool scheduler and the initial scheduler are
different.

Correct this by destroying the domain's scheduling information
before removing it from the pool.
