Russell King af4cb25df9 ARM: uaccess: fix undefined instruction on ARMv7M/noMMU
The use of get_domain() in copy_thread() results in an oops on
ARMv7M/noMMU systems.  The thread cpu_domain value is only used when
CONFIG_CPU_USE_DOMAINS is enabled, so there's no need to save the
value in copy_thread() except when this is enabled, and this option
will never be enabled on these platforms.
