uml: remove unused variables in the context switcher
This patch removes a variable which was not used in two functions. Yet
another code cleanup, nothing really significant.
Please note that I could not test this on x86_64. I don't have the
hardware for it.
[ jdike - Bits of tidying around the affected code. Also, it's fine on
x86_64 ]
