microblaze: fix get_user/put_user side-effects

The Microblaze implementations of get_user() and (MMU) put_user() evaluate
the address argument more than once. This causes unexpected side-effects for
invocations that include increment operators, i.e. get_user(foo, bar++).

This patch also removes the distinction between MMU and noMMU put_user().

Without the patch:
  $ echo 1234567890 > /proc/sys/kernel/core_pattern
  $ cat /proc/sys/kernel/core_pattern
  12345
